Answer 3

To solve the expression $(-3m + 5)^2$, you need to perform the following steps:

Step 1: Expand the expression using the formula for squaring a binomial: $(a - b)^2 = a^2 - 2ab + b^2$

In this case, $a = -3m$ and $b = 5$, so we have: $(-3m + 5)^2 = (-3m)^2 - 2(-3m)(5) + 5^2$

Step 2: Simplify the expression: $(-3m)^2 = 9m^2$ (square of a negative number is positive) $-2(-3m)(5) = 30m$ (negative times negative is positive) $5^2 = 25$ (5 squared)

Putting it all together: $(-3m + 5)^2 = 9m^2 + 30m + 25$

So, the simplified expression is $9m^2 + 30m + 25$.
