Question

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

Answer 1

The factors of given quadratic equation

`x = (9)/(15) and x = -2`

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

`x = (9)/(15) and x = -2`
