This is the polynomial equation and rewrite the middle term as a sum of two terms whose products is a*c=10*-6 and whose sum is b = -11
Factor -11 out of -11X
10X² - 11(X) - 6
Rewrite 11 as 15 + 4
10 x² + (-15 + 4)x -6
10x² -15x + 4x -6
Factor out the greatest common factor from each group.
5x(2x - 3) +2(2x - 3)
(5x + 2) (2x - 3)
