Simplifying f(x) = x2 + 6x + 7 Multiply f * x fx = x2 + 6x + 7 Reorder the terms: fx = 7 + 6x + x2 Solving fx = 7 + 6x + 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 = 7x-1 + 6 + x Simplifying f = 7x-1 + 6 + x Reorder the terms: f = 6 + 7x-1 + x
