FACTORIZATION - 6


Factorize 6x2 + 7x - 5

Solution

= 6x2 + 7x - 5.  ---- We split the middle term (+7x) to be (-3x + 10x).

= 6x2 - 3x + 10x – 5             -----   (-3x) = -14x + 5x.

= (6x2 -3x) + (10x - 5)   ---- grouping the factors.       

= 3x(2x - 1) + 5(2x - 1)

= (3x + 5) (2x -1)

Hence 6x2 + 7x - 5= (3x + 5) (2x -1)answer.

TRY THIS…..


Factorize 14x2 + 3x – 2.
