10x^2 + 11x - 6

= 10x^2 + 15x - 4x - 6

= 5x(2x + 3) - 2(2x + 3)

10x^2 + 11x - 6 = 0

is the solution to

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

which is

= 10x^2 + 15x - 4x - 6

= 5x(2x + 3) - 2(2x + 3)

**= (5x - 2)(2x + 3)**Thus the solution to10x^2 + 11x - 6 = 0

is the solution to

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

which is

**x = 2/5 or x = -3/2**
