Question

Solve the following equations by using the Quadratic formula and answer the
subsequent questions:
1
12x2 + 5x - 2 = 0​

Answer 1

12x² + 5x -2 = 0

12x² + (8-3)x -2 = 0

12x² + 8x - 3x - 2 = 0

4x (3x + 2) -1 (3x + 2) = 0

(4x - 1) (3x + 2) = 0

4x - 1 = 0

4x = 1

x = 1/4

3x + 2 = 0

3x = -2

x = -2/3
