2(-2)^2 + 3(-3)^3 - (-2)^2 + 4(5)^2 - (-2)^2
Okay, all the variables are accounted for now. Lets do the exponents now.
(-2)^2 = 4
(-3)^3 = -27
(5)^2 = 25
Let's fill in the missing values:
2(4) + 3(-27) - (4) + 4(25) - (4)
Multiply what needs to be multiplied.
(8) + (-81) - (4) + (100) - (4)
The (8) is cancelled out by the two - (4)s.
(-81) + (100)
100 - 81 = 19
Your answer is 19
Yep, just fixed it now Alan
