Question 2248
>> {{{x(x-6)(x-6)/x}}} - {{{x(x-6)(x+6)/(x-6)}}} = {{{x(x-6)(6)/x}}}


>> {{{(x-6)(x-6)}}} - {{{x(x+6)}}} = {{{(x-6)(6)}}}


>> {{{x^2-6x-6x+36}}} - {{{x^2-6x}}} = {{{6x-36}}}


>> {{{x^2-12x+36}}} - {{{x^2-6x}}} = {{{6x-36}}}


>> {{{x^2 - x^2 - 12x - 6x + 36}}} = {{{6x-36}}}


>> {{{-18x + 36}}} = {{{6x-36}}}


>> {{{-18x - 6x}}} = {{{-36 - 36}}}


>> {{{-24x}}} = {{{-72}}}


>> {{{-24x/-24}}} = {{{-72/-24}}}


>> x = 3
