Question 105094
always remember this!---{{{a^2+b^2=(a-b)(a+b)}}}

It can be applied to this equation.

Here,{{{a=x}}} and {{{b=6}}}.

Thus,

{{{x^2-36=(x+6)(x-6)}}}


CHECK:
{{{(x+6)(x-6)=x(x-6)+6(x-6)}}}
{{{(x+6)(x-6)=(x^2-6x)+(6x-36)}}}
{{{(x+6)(x-6)=x^2+(-6x+6x)-36}}}
{{{(x+6)(x-6)=x^2+0-36}}}
{{{(x+6)(x-6)=x^2-36}}}

Therefore, my solution is correct!
