x²-x-156
=x²-13x+12x-156
=x(x-13)+12(x-13)
=(x-13)(x+12)
Hope it helps u and make it as brainliest!

Given, x² - x - 156 = 0
⇒ x² - 13x + 12x - 156 = 0
⇒ x ( x - 13 ) + 12 ( x - 13 ) = 0
⇒ ( x - 13 ) ( x + 12 ) = 0
⇒ x = -12 (or) 13
∴ x² - x - 156 = ( x - 13 ) ( x + 12 )
Hope my answer helps you : )
⇒ x² - 13x + 12x - 156 = 0
⇒ x ( x - 13 ) + 12 ( x - 13 ) = 0
⇒ ( x - 13 ) ( x + 12 ) = 0
⇒ x = -12 (or) 13
∴ x² - x - 156 = ( x - 13 ) ( x + 12 )
Hope my answer helps you : )
