FACTORIZATION C6

Factorize 4x² - 19x - 30.

Solution

= 4x² - 19x - 30. We split the middle term (-19x) to be (-5x - 24x).

= 4x² - 5x - 24x - 30.

= (4x² - 5x) – (24x – 30).

= x(4x - 5) – 6(4x - 5).

= (x - 6) (4x - 5)

Hence 4x² - 19x - 30. = (x - 6) (4x - 5) answer.

TRY THIS…..

7x² - 15x + 2.
