A) $121 x ^ { 2 } - 264 x - 144$
B) $121 x ^ { 2 } + 264 x - 144$
C) $x ^ { 2 } - 144$
D) $121 x ^ { 2 } - 144$

Question

Quizplus · Accepted Answer

This problem uses the difference of squares formula, $a^2 - b^2 = (a + b)(a - b)$. Here, $a = 11x$ and $b = 12$, so the expression simplifies to $(11x)^2 - (12)^2 = 121x^2 - 144$.

Solve the Problem (11x+12)(11x−12)( 11 x + 12 ) ( 11 x - 12 )(11x+12)(11x−12)
