Simplifying f(x) = x2 + 8x + -20 Multiply f * x fx = x2 + 8x + -20 Reorder the terms: fx = -20 + 8x + x2 Solving fx = -20 + 8x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = -20x-1 + 8 + x Simplifying f = -20x-1 + 8 + x Reorder the terms: f = 8 + -20x-1 + x
