If the root of the equation for X: 2x ^ 2-ax-b = 3-2x is - 2, then 3-4A + 2B =? As soon as possible! ^This symbol is To the power of

If the root of the equation for X: 2x ^ 2-ax-b = 3-2x is - 2, then 3-4A + 2B =? As soon as possible! ^This symbol is To the power of

If the root of 2x ^ 2-ax-b = 3-2x is - 2, then
2*（-2）^2-a(-2)-b=3-2(-2)
8+2a-b=7
2a-b=-1
3-4a+2b
=3-2(2a-b)
=3-2*(-1)
=3+2
=5
