Question

a^2-b^2-6b-9 , factorize​

Answer 1

Step-by-step explanation:

=a²-b²-6b-9

=a²-(b²+6b+9)

=a²-(b+3)²

=(a+b+3)(a-(b+3))

=(a+b+3)(a-b-3)

Answer 2

The factorization would be

a²-b²-6b-9

a²-(b²+6b+9)

a²-(b+3)²

Here this is look like x²-y²

Therefore,

a²-(b+3)²

{a+(b+3)} {a-(b+3)}

(a+b+3)(a-b+3)

Here is your factorization.
