Answer 2

Answer:

The answer is $(11x-6y)^{2}$

i hope this helps!!

Step-by-step explanation:

1. $11^{2} = 121$ so $121x^{2} = (11x)^{2}$ (we take the square out). we can take $132x$ as $2$ × $11x$ × $6y$. and $36 = 6^{2}$ so $36y^{2} = (6y)^{2}$ (we take the square out again)

2. since $(a+b)^{2} = a^{2} + 2ab + b^{2}$ it becomes $(11x-6y)^{2}$
