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.
