5x^2 - 2x - 3 = 0
5x^2 - 2x - 3 = (5x + 3)(x - 1)

(5x + 3) = 0;
5x = -3;
x = -3/5

(x - 1) = 0;
x = 1

x = (-3/5, 1)

(x + 1)^2 = 9;

x^2 + 2x + 1 = 9;

x^2 + 2x + 1 - 9 = 0;

x^2 + 2x - 8 = 0

x^2 + 2x - 8 = (x + 4)(x - 2)

(x + 4) = 0; x = -4;
(x - 2) = 0; x = 2

x = -4 or x = 2

12x^2 - 3x - 9 = 0
12x^2 - 3x - 9 = 3(4x + 3)(x - 1)

3(4x + 3) = 0;
12x + 9 = 0;
12x = 0 - 9;
x = -9/12 = -3/4

(x - 1) = 0;
x = 1

x = {-3/4, 1}

x^2 - 56 = 10x;

x^2 - 10x - 56 = 0;

(x + 4)(x - 14) = 0
(x + 4) = 0; x = -4;
(x - 14) = 0; x = 14

the solution set is {-4, 14}
