Simplifying f(x) = x3 + -1x2 + -4x + 4 Multiply f * x fx = x3 + -1x2 + -4x + 4 Reorder the terms: fx = 4 + -4x + -1x2 + x3 Solving fx = 4 + -4x + -1x2 + x3 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = 4x-1 + -4 + -1x + x2 Simplifying f = 4x-1 + -4 + -1x + x2 Reorder the terms: f = -4 + 4x-1 + -1x + x2
