Question

Quizplus · Accepted Answer

This is an application of the difference of squares formula, $a^2 - b^2 = (a+b)(a-b)$. Here, $a = 5a$ and $b = 11c$, so the product is $25a^2 - 121c^2$.

Multiply - (5a+11c)(5a−11c)(5 a+11 c)(5 a-11 c)(5a+11c)(5a−11c) A) 25a2−110ac−121c225 a^{2}-110 a c-121 c^{2}25a2−110ac−121c2
