-(5a + b)(5a - b)

Question

Quizplus · Accepted Answer

This problem can be solved using the special product formula (a+b)(a-b) = a^2 - b^2. In this case, let 5a be our a and b be b. Then, we can rewrite the expression as (5a)^2 - b^2. Simplifying, 25a^2 - b^2. Therefore, the answer is 11ebb63d_1b9b_6105_b851_cd74d4152b5c_TB8475_11. We can use the special product formula (a+b)(a-b)=a^2-b^2, where a=5a and b=b. 
So, (5a+b)(5a-b) = (5a)^2 - b^2 = 25a^2 - b^2. 
Therefore, the answer is B, 11ebb63d_1b9b_6105_b851_cd74d4152b5c_TB8475_11.
