Question 31239
{{{x^2 - (4/5x)(30/(3x-6))}}}
={{{x^2 - (4*30)/(5x*(3x-6))}}} ,we multiply across
={{{x^2 - (120/(15x^2-30x))}}} ,simplify
={{{x^2 - (120/15x(x-2)}}} ,simplify
={{{x^2 - (8/x(x-2))}}} ,reduce
={{{x^2(x(x-2)/x(x-2) - (8/x(x-2))}}} ,multiply x^2 by x(x-2)/x(x-2)
={{{(x^2(x(x-2)-8)/x(x-2)}}} ,subtract with same denominator
