<u><em>Explanation:-</em></u>
<em>Given quadratic equation 15x² +39 x -18 =0</em>
<em> The factors of 270 = 30 × 9</em>
<em>The quadratic equation 15x² +39 x -18 =0</em>
<em> ⇒ 15 x² +30 x-9x -18=0</em>
<em> ⇒ 15x(x+2) -9( x+2) =0</em>
<em> ⇒( 15x -9)(x+2) = 0</em>
<em> 15x - 9=0 and x+2 =0</em>
<em> 15 x =9 and x = -2</em>
