Simplifying f(x) = x2 + 8x + -68 Multiply f * x fx = x2 + 8x + -68 Reorder the terms: fx = -68 + 8x + x2 Solving fx = -68 + 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 = -68x-1 + 8 + x Simplifying f = -68x-1 + 8 + x Reorder the terms: f = 8 + -68x-1 + x
