Which of the binomials below is a factor of this expression?
64a2 - 81b2

B

Step-by-step explanation:

This is the difference of perfect squares, which follows a pattern of

(A+B)(A-B)

We have 64, which is 8-squared,

we have A squared, which is A squared ( :/ )

we have 81, which is 9-squared, and

we have B-squared, which is B squared.

We can factor this then following the pattern into:

(8A+9B)(8A-9B)

Choice B only matches one of our binomials.
