Question

Transform the polynomial into a perfect square trinomial to solve

x^2-12x=13
a){46,55}
b){-1,13}
c){-15,27}
d){-21,33}

Answer 1

If you would like to solve x^2 - 12 * x = 13, you can do this using the following steps:

x^2 - 12 * x = 13
x^2 - 12 * x - 13 = 0
(x - 13) * (x + 1) = 0
1. x = 13
2. x = -1

The correct result would be b) {-1, 13}.
