You have a rational expression (a fraction) on the left side of the equation. Perform the long division. (Divide (x - 3) into (-2x^3+5x^2-4).) Next compare that answer to the division with the right side of the equation. This will tell you what the values of a, b, c, and d are. Finally, just plug those values into -4a - b+2c-d to get the answer.
