Need help to solve equation and complete square x^2+2x-35=0?
A) √-35, -√-35 B) -28,-7 C) 5,-7 D)-5,7
A) √-35, -√-35 B) -28,-7 C) 5,-7 D)-5,7
-
x^2 + 2x - 35 = 0
(x + 1)^2 -36 = 0
(x + 1)^2 = 36
x + 1 = +/- 6
x = -1 +/- 6
x = 5 & -7
(x + 1)^2 -36 = 0
(x + 1)^2 = 36
x + 1 = +/- 6
x = -1 +/- 6
x = 5 & -7
