can someone tell me what I am doing wrong with this problem:
x^2 + 10x +13 = 0
x^2 +10x + 13 -13 = 0 - 13
x^2 + 10x = -13
x^2 + 10x + 25 = -13 + 25
(x + 5)^2 = 12
x + 5 = ±(sqrt)12
x^2 + 10x +13 = 0
x^2 +10x + 13 -13 = 0 - 13
x^2 + 10x = -13
x^2 + 10x + 25 = -13 + 25
(x + 5)^2 = 12
x + 5 = ±(sqrt)12
