Question

Use the difference-of-squares pattern to factor the following.
4a^2 − (1b + 3)^2

Answer 1

Difference of Squares Pattern
--------------------------
(x^2 -y^2) = (x + y)(x - y)

(2a)^2 - (b + 3)^2 = [(2a) + (b + 3)] [(2a) - (b +3)] =

Clean those up and post results here. I'll check.

Answer 2

(2a+2a)(b+3)

Answer 3

[(2a) + (b + 3)] [(2a) - (b +3)] =

[2a + b + 3] [ 2a - b - 3]

Answer 4

[(2a+b+3)(2a-b-3)]
Can you write it like that?

Answer 5

Yes.
