Answer:
11
Step-by-step explanation:
Lets plug in -2 for x
Remember that a negative number times a negative number is positive, so (-2)² is positive 4. Also remember subtracting by a negative means you are adding the number.
[tex]4x^2 - x - 7 \\\\4(-2)^2 - (-2) - 7 \\\\4(4) + 2-7\\\\16 -5\\\\11[/tex]
So the answer is 11
