x^2 + 2x - 35 = 0
-35 = -1*35 = -5*7.
Choose the pair of factors whose sum =
2, the coefficient of X.
(x-5)(x+7) = 0
x-5 = 0
X = 5.
x+7 = 0
X = -7.
Solution Set: X = -7, and 5.
Can you please help with the following:
x^2+2x-35=0
I can't remember how to get the different possibilities.
Appreciate help, thanks
