Question 1088127
{{{((x^2-100)/(x^2+2x-120))/((6x+60)/(x-2))=((x^2-100)/(x^2+2x-120))*((x-2)/(6x+60))}}}
{{{((x^2-100)/(x^2+2x-120))/((6x+60)/(x-2))=(((x-10)(x+10))/((x+12)(x-10)))*((x-2)/(6(x+10)))}}}
{{{((x^2-100)/(x^2+2x-120))/((6x+60)/(x-2))=((cross(x-10)cross(x+10))/((x+12)cross(x-10)))*((x-2)/(6(cross(x+10))))}}}
{{{((x^2-100)/(x^2+2x-120))/((6x+60)/(x-2))=(x-2)/(6(x+12))}}}
