Question

Which of the binomials below is a factor of this expression?

100A²-498²
OA. A+ 7B
OB. 10A+7B
OC. A + B
OD. 10A+B

Answer 1

Answer: B. 10A + 7B

Explanation:

To find the correct binomial, we will factor the given expression. I assume that by "-498²" you mean "-49B²".

This is a difference of squares:

(10A + 7B)(10A - 7B)

The binomial 10A + 7B is an answer option, so our answer is:

B. 10A + 7B
