x%5E2+-+%284%2F5x%29%2830%2F%283x-6%29%29
=x%5E2+-+%284%2A30%29%2F%285x%2A%283x-6%29%29 ,we multiply across
=x%5E2+-+%28120%2F%2815x%5E2-30x%29%29 ,simplify
=x%5E2+-+%28120%2F15x%28x-2%29 ,simplify
=x%5E2+-+%288%2Fx%28x-2%29%29 ,reduce
=x%5E2%28x%28x-2%29%2Fx%28x-2%29+-+%288%2Fx%28x-2%29%29 ,multiply x^2 by x(x-2)/x(x-2)
=%28x%5E2%28x%28x-2%29-8%29%2Fx%28x-2%29 ,subtract with same denominator
