FACTORIZATION C3

Factorize 8x2 + 11x + 3.

Solution

= 8x2 + 11x + 3. We split the middle term (11x) to be (8x + 3x).

= 8x2 + 8x + 3x + 3

=  (8x2 + 8x) + (3x + 3) we group by using brackets.

= 8x(x + 1) + 3(x + 1).

= (8x + 3) (x + 1)


Hence 7x2 + 9x + 2 = (8x + 3) (x + 1) answer.


TRY THIS…..

8x2 + 13x + 5.
