Solve 3x squared - 12x equals -12?

Answer 1

If your equation was 3x^2 - 12x = -12, then it is true you may factorize the terms as the previous contributer did before (3x - 6)(x - 2). But since there was no answer I will pick up where he/she left off and solve the equation using a somewhat different approach instead.

3x^2 - 12x = - 12

<=>

x^2 - 4x = - 4

<=>

(x-2)^2 - 4 = -4

<=>

(x-2)^2 = -4 + 4

<=>

(x-2)^2 = 0

<=>

x = 2

Answer: {2}
