Simplifying f(x) = x5 + -5x3 + 4x Multiply f * x fx = x5 + -5x3 + 4x Reorder the terms: fx = 4x + -5x3 + x5 Solving fx = 4x + -5x3 + x5 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = 4 + -5x2 + x4 Simplifying f = 4 + -5x2 + x4
