Simplifying f(x) = -2x2 + 8x + -5 Multiply f * x fx = -2x2 + 8x + -5 Reorder the terms: fx = -5 + 8x + -2x2 Solving fx = -5 + 8x + -2x2 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 + 8 + -2x Simplifying f = -5x-1 + 8 + -2x Reorder the terms: f = 8 + -5x-1 + -2x
