Question

Factorize 16-25(b+3)^2

Answer 1

Hi,

Here's ur answer :-

16- 25(b+3)^2

= 16- 5^2(b+3)^2

= 16- {5(b+3)}^2

= 4^2- {5(b+3)}^2

= 4^2- (5b+ 15)^2

(using a^2 - b^2 = (a+b)(a-b))

= (4+5b+15)(4-5b-15)

= (5b + 19)(-5b-11)

(-1 is taken common from right side)

= -(5b+19)(5b+11)

This is the answer

HOPE IT HELPS (^_^)
