Simplifying F(X) = -1x3 + 6x2 + -9x Multiply F * X FX = -1x3 + 6x2 + -9x Reorder the terms: FX = -9x + 6x2 + -1x3 Solving FX = -9x + 6x2 + -1x3 Solving for variable 'F'. Move all terms containing F to the left, all other terms to the right. Divide each side by 'X'. F = -9xX-1 + 6x2X-1 + -1x3X-1 Simplifying F = -9xX-1 + 6x2X-1 + -1x3X-1
