✐Explanation✐
Multiply each term by term.
35 + 5√2 - 7√2 - 2
Combine like terms to get a solution.
33 - 2√2
(5-â2)(7+â2)
5*7 + 5*â2 - 7*â2 - â2*â2
35 + 5 â2 - 7â2 - 2
33 - 2â2
one way is to use FOIL.
5 x 7 = 35
5 x 2^1/2
-7 x 2^1.2
-2
sum up:
33 -2 times the square root of 2
35 +5â2 - 7â2 - 2
Have a good day!
35 + 5sqrt(2) - 7sqrt(2) - 2 = 33 - 2sqrt(2)
