Respuesta :
i think the answer is -8
because -2x2 is -4 and 4x-2 is -8
so if you did -4+-8+4 it would equal -8
because -2x2 is -4 and 4x-2 is -8
so if you did -4+-8+4 it would equal -8
Answer:
Step-by-step explanation:
Substitute by writing the following equation.
When you say x2, do you mean x squared? If yes, then use this following equation.
(-2)^2 + 4(-2) + 4
4 + -8 + 4
8 - 8 = 0
If it is not squared, then use this following equation.
2(-2) + 4(-2) + 4
-4 + -8 + 4
-12 + 4 = -8
