Question

3m^2 + 2m If ( m = -5 ) Evaluate each expression

Answer 1

We have to evaluat 3m²+2m when m = -5.

To do that we replace m with its value, -5, and solve:

`\begin{gathered} 3m^2+2m \\ 3(-5)^2+2(-5) \\ 3\cdot25-10 \\ 75-10 \\ 65 \end{gathered}`

Answer: the expression is equal to 65 when m = -5.
