-3m(m+8)

explain

To simplify -3m(m+8), we can use the distributive property of multiplication to distribute the -3m to both terms inside the parenthesis:

-3m(m+8) = -3m * m + (-3m) * 8

= -3m^2 - 24m

So, the simplified expression of -3m(m+8) is -3m^2 - 24m.

To simplify the expression -3m(m+8), we need to perform the multiplication and combine like terms, if possible.

First, we'll multiply -3m by each term inside the parentheses, m and +8.

-3m * m = -3m^2
-3m * 8 = -24m

Now, we can rewrite the expression:

-3m(m+8) = -3m^2 - 24m

So, the simplified expression is -3m^2 - 24m.
