Simply multiply the terms and then multiply the final expression by the given constant.
Start with (x - 2)*(x - 3) = x^2 - 5x + 6
Multiply this by (x - 4) to get x^3 - 5x^2 + 6x - 4x^2 +20x - 24
Simplify to x^3 - 9x^2 + 26x - 24
Continue the process until all factors have been multiplied---then multiply each term by -2
