Please help me with this problem

To evaluate this expression, we simply plug the value of the variable into the expression and solve.

Since m = -4, plug a -4 in for m every time the m appears in the expression.

So we have (-4)^2 + 6(-4) + 3.

Start by simplifying the exponent.

(-4)^2 is 16.

Now multiply.

A positive times a negative is a negative.

So 6(-4) is -24.

So we have 16 + 24 + 3 which is 43.
