Simplifying f(x) = x2 + -10x + 89 Multiply f * x fx = x2 + -10x + 89 Reorder the terms: fx = 89 + -10x + x2 Solving fx = 89 + -10x + 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 = 89x-1 + -10 + x Simplifying f = 89x-1 + -10 + x Reorder the terms: f = -10 + 89x-1 + x
