Question

Quizplus · Accepted Answer

To square the binomial $(-6m^2 - 9n)^2$, we use the formula $(a - b)^2 = a^2 - 2ab + b^2$, where $a = -6m^2$ and $b = 9n$. Squaring each term and multiplying gives $36m^4 + 108m^2n + 81n^2$.

Multiply - (−6m2−9n)2\left( - 6 m ^ { 2 } - 9 n \right) ^ { 2 }(−6m2−9n)2

Multiply
- $\left( - 6 m ^ { 2 } - 9 n \right) ^ { 2 }$
