Factor the quadratic equation 0=15x squared + 39 x-18

The factors of given quadratic equation

Step-by-step explanation:

Explanation:-

Given quadratic equation 15x² +39 x -18 =0

The factors of 270 = 30 × 9

The quadratic equation 15x² +39 x -18 =0

                                   ⇒ 15 x² +30 x-9x -18=0

                                ⇒ 15x(x+2) -9( x+2) =0

                               ⇒( 15x -9)(x+2) = 0

                      15x - 9=0    and  x+2 =0

                      15 x =9   and  x = -2
