Mauricio · Answer 1

x = 4 or x = - 10 for equation x^2 + 6x = 40

Step-by-step explanation:

x^2 + 6 = 40

x^2 = 40 - 6

x^2 = 34

x = root (34) or x = - root (34) but this is not in the answer choice.

is it x^2 + 6x = 40

x^2 + 6x + 9 = 40 + 9

(x + 3) ^2 = 49

x + 3 = 7 or x + 3 = - 7

x = 4 or x = - 10
