Q: Solve the quadratic equation by factoring. 5x2 - 8 = 39x
A: 5x^2 - 8 = 39x; 5x^2 - 39x - 8 = 0; (5x + 1)(x - 8) = 0; 5x + 1 = 0; 5x = -1; x = -1/5; x - 8 = 0; x = 8 x = -1/5 or x = 8

5x^2 - 8 = 39x;
5x^2 - 39x - 8 = 0;
(5x + 1)(x - 8) = 0;
5x + 1 = 0; 5x = -1; x = -1/5;
x - 8 = 0; x = 8

x = -1/5 or x = 8

12x^2 - 10x - 42 = 0
2(2x + 3)(3x - 7) = 0;
2(2x + 3) = 0; 4x + 6 = 0; 4x = -6; x = -6/4; x = -3/2
3x - 7 = 0; 3x = 7; x = 7/3
Solution: x = -3/2 or 7/3
