The value of the expression is $-44$.
Answer for screen readers
The final answer is $-44$.
Steps to Solve
- Substitute the value of q
First, substitute $q = -1$ into the expression $-44q^2$.
$$ -44(-1)^2 $$
- Calculate the square of q
Next, calculate $(-1)^2$.
$$ (-1)^2 = 1 $$
- Multiply by -44
Now, multiply $-44$ by the result from the previous step.
$$ -44 \times 1 = -44 $$
The final answer is $-44$.
