Question

factorise the following quadratic polynomial by splitting middle term x square +6x -216

Answer 1

Solution :

_____________________________________________________________

Given :

To factorize x² + 6x - 216 by splitting the middle term,.

_____________________________________________________________

We can write the given equation as follows :

⇒ x² + 6x - 216

⇒ x² - 12x + 18x - 216            (As, -12 + 18 = 6,.  12× 18 = 216)

⇒ x (x - 12) + 18 (x - 12)

⇒ (x + 18)(x - 12)
