FACTORIZATION 2


Factorize 2x2 - 9x - 35

Solution

= 2x2 - 9x – 35.  We split the middle term (-9x) to be (-14x + 5x).

= 2x2 - 14x + 5x – 35                (-3x) = -14x + 5x.

= (2x2 -14x) + (5x - 35)

= 2x(x - 7) + 5(x - 7)

= (2x + 5) (x -7)

Hence 2x2 - 9x – 35 = (2x + 5) (x - 7) answer.

TRY THIS…..


Factorize 7x2 - 27x – 4.
