write the simplified expression

4x^2-2+8-3(4x^2-2)+(-x^2+3x-2)

PLEASE PLEASE PLEASE
include all the steps if you can

what steps? remove parentheses, collect like terms

4x^2-2+8-3(4x^2-2)+(-x^2+3x-2)
4x^2-2+8 -12x^2+6 -x^2+3x-2
(4-12-1)x^2 + (3)x + (-2+8+6-2)
-9x^2 + 3x + 10

I suspect a typo in the first expression (4x^2-2+8), but you fix it and correct the calculations.
