Verified answer

ax² + bx + c = 0

1x² + 70x - 100000 = 0

a = 1

b = 70

c = -100000

delta

d² = b² - 4ac

d² = 70² - 4*1*(-100000)

d² = 404900

d = 636,3175

x1 = (-70 + 636,3175)/2 = 283,16

x2 = (-70 - 636,3175)/2 = -353,16

pronto

a =1, b=70 e c = -100000

=============================

delta = 4900 + 400000 = 404900

raiz(delta) = 636,32

B1 = (-70 + 636,32) / 2 = 566,32/2 = 283,16

B2 = (-70 - 636,32) / 2 = -706,32/2 = -353,16

a = 1

b = 70

c = -100000

no caso seria B' e B"

a = 1

b = 70

c = -1000000

∆=b²-4ac

∆ = 70² - 4(1)(-100000)

∆= 4900 + 400000

∆= 404.900

B = (-b±√∆)/2a

B'=(-70-632,32)/2

B'=-353,16

B"=(-70+632,32)/2

B"=283,16

A formula

x=(-b+-Vdelta)/2a

Em

B² + 70B - 100000= 0

a=1

b=70

c=-100000

delta= 70²+4.100000=404.900 ...Vdelta= 632,32

x=(-70-632,32)2

x=-353,16

x=(-70+632,32)/2

x=283,16
