Simplifying f(x) = x2 + x + -5 Multiply f * x fx = x2 + x + -5 Reorder the terms: fx = -5 + x + x2 Solving fx = -5 + x + 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 = -5x-1 + 1 + x Simplifying f = -5x-1 + 1 + x Reorder the terms: f = 1 + -5x-1 + x
