1) (x + 3)(x - 3) < 0

2) 2 (x - 2)(x - 7) > 0

3) (x - 1)(x + 9) ≤ 0

4) x²+5x+6≤0

ó

4) (x + 5)(x + 1) ≤ 0

Es lamentable el uso de guiones gramaticales

delante de fórmulas,

se confunde con signos menos

Todos estas desigualdades se solucionan

de la misma manera

Consideramos el producto

(x - a) (x - b)

con a; b ordenados de menor a mayor.

Los cambios de signo

se deben dar cuando se anula el producto

es decir, en x = a ; x = b

Las desigualdades estrictas son

x < a

(x - a) (x - b) > 0

porque hay 2 factores negativos

a < x < b

(x - a) (x - b) < 0

porque hay 1 factor negativo

b < x

(x - a) (x - b) > 0

porque hay 0 factores negativos

En total, los signos estrictos son

x < a U b < x

(x - a) (x - b) > 0

a < x < b

(x - a) (x - b) < 0

Nota:

Este análisis sirve, mutatis mutandi,

para más factores en el producto,

alternando signos desde el último intervalo positivo.

Ahora, a los problemas

1) (x + 3)(x - 3) < 0

Solución

-3 < x < 3

ó

(-3 ; 3)

2) 2 (x - 2)(x - 7) > 0

El 2 no afecta porque es positivo

Solución

x < 2 U 7 < x

ó

(-inf ; 2) U (7 ; +inf)

3) (x - 1)(x + 9) ≤ 0

Ordenamos las raíces

(x + 9)(x - 1) ≤ 0

Solución

9 ≤ x ≤ 1

ó

[ -9 ; 1 ]

4) x² + 5 x + 6 ≤ 0

ó

4) (x + 3)(x + 2) ≤ 0

Solución

-3 ≤ x ≤ -2

ó

[ -3 ; -2 ]

¿1)- (x+3)(x-3)< 0 como resolver esta desigualdad cuadratica? NATO will nuke Ukraine to blame Russia for it; then NATO will nuke Russia from Scandinavia. China will attack Russia; but will not get past Ural Mountains. Russia will destroy Turkey and America. China will have a hole across the whole country to the abyss. Only Eurasia and Alaska (both without coasts) will remain after demons blow up Antarctica (which surrounds the flat earth) and Greenland melts. Move to Ural Mountains or inland Alaska. Sionists want war between Russia and Germany over Serbia from June to October on their holidays because (666 times 3)+(6 times 3) = 2016 (in their twisted logic).

Tube people = demons. Clones = demons. Human costumes that demons wear = demons. Dinosaurs and 666ed people have triple stranded DNA; normal person can't swallow 666ed food (designed for 666ed people). Demons live inside clones. Bacteriologist Alexandre Yersin (who discovered Bubonic plague) is depicted on the Shroud of Turin. There is another shroud on which blasphemer Yosef (who was crucified on a pole in 1066 AD) is depicted. Menachem Mendel Schneerson, Lenin (el=deity in Hebrew, nine = no in German; so, when chanted repeatedly is blasphemy against the Creator), and Yosef were possessed by Azazel; now, Rico Cortes is possessed by Azazel.

WW3 happens; 7% of people will be left; after people are tired of war, they will elect the antichrist as one world leader; don't vote. ISIS stands for Israeli Secret Intelligence Service. Next false flag: Statue of Liberty in order to attack Iran. Move away from coasts as nukes will go off in the ocean (at where tectonic plates meet; result: megatsunamis 1km high).

Wear natural clothing so that if a bomb goes off it won't stick to the body as fast as synthetic clothes. All metal will be burned for fuel; so, save knives, crowbars, shovels, wood-burning stoves, etc. Also, save cloth/fabric/textile to cover the wounds and diseases.

Eat natural food because nanochips, cells of aborted fetuses, bug DNA, and other poisons are in food that is commonly sold. Seraphim of Sarov and Sergiy of Radonezh will be resurrecred after WW3 for a short time; Seraphim of Sarov will show the new Ruski Tsar who will fight the antichrist for about 2 years and 8-10 months.

Earth is flat; stands on 3 pillars (the Most Holy Trinity); pillars stand on water at zero Kelvin. Zodiac is planetary prison of demons; don't believe in horoscopes or you'll exhibit the traits of the trapped demons. Most thoughts and dreams are from demons; demons never do good. Sleep fully clothed; pray the Jesus prayer. Pray to your guardian angel to have normal sleep.

Humans were created about 7525 years ago. Ruski Orthodox Christian Vyacheslav Krasheninnikov was the last prophet before Enoch and Elijah return to preach against the antichrist.

Birds participate in time creation. It's a sin to kill birds. Dinosaurs live under our level. They will get out through sinkholes and lakes. To kill them, go for their nerves. Save the birds; but kill the dinosaurs. First dinosaur will come out of Volga River in Russia.

Demons grow human skin (from a sample taken during abduction) and put it on so as to look like us. Demons will invite people to be healed inside their UFOs; those who go will be like zombies after. Gov't provides demons with diamonds and allows demons to abduct people. If you're being abducted, slowly pray the Jesus prayer.

Don't panic. Demons use diamonds and souls to power their UFO craft. The bigger the diamond, the more it lasts. Demons have 4 UFO bases: 1)Moon 2)Inside fake mountain Kailash in Tibet 3)In lake Baikal in Russia 4)In Atlantis which is underneath the Mariana Trench in Pacific Ocean. There are no aliens. Nobody lives on other planets.

Airplanes that go down are hit by demons because they need the airspace to fight Jesus. Antichrist is pale with red eyes. He's possessed by Satan since he's 12 years old. He flies. He wears gloves to hide long nails. He's surrounded by demons who appear as angels of light.

Don't go into a UFO to be healed by demons. Green 666 is given by isotope rays on wrist or forehead when people stretch hands to receive small plastic grey card with no name on it (World Passport). Police will microchip and isotope ray people on the highways. Microchipped people will be influenced by computers to take grey plastic card; but when they do, 666 is given. Food stores will isotope ray people too. Antichrist will also release prisoners to mark people. Reject 666 at all cost because it leads to permanent hell.

If you're about to be marked, pray the Jesus prayer. Hide with Orthodox Christians to escape 666; leave all electronics behind so that antichrist's minions can't track you. Give to charity in the name of Archangel Michael; he rescues people from temporary hell twice a year (or brings them up a level, that is, to a level with less punishment; eventually, people are freed). Feed the pigeons; when pigeons bow down, people are saved from temporary hell. Forgive me.
