User: Solve the quadratic equation 2x^2 + 2x - 12 = 0

Weegy: |2x - 5| = 4;
2x - 5 = 4;
2x = 4 + 5;
2x = 9;
x = 9/2

2x - 5 = -4;
2x = -4 + 5;
2x = 1;
x = 1/2

Solutions are x = 9/2 or x = 1/2

2x^2 + 2x - 12 = 0;
2(x - 2)(x + 3) = 0;
2(x - 2) = 0;
2x - 4 = 0;
2x = 4;
x = 4/2 = 2;
x + 3 = 0; x = -3;
The solution set is x = -3 or x = 2
