Assuming that this is what you mean by factoring, you can proceed as follows: subtracting 36 from both sides gives
[tex](x+5)^2-36=0[/tex]
This is a difference of squares, since 36 is 6 squared. We can factor it using the formula [tex]a^2-b^2=(a+b)(a-b)[/tex]
[tex](x+5)^2-36=0 \iff (x+5+6)(x+5-6)=0 \iff (x+11)(x-1)=0[/tex]
A product is zero if and only if one of the factors is zero:
[tex]x+11=0 \iff x=-11,\quad x-1=0 \iff x=1[/tex]
