n%5E2%2B5n%2B6=+%28n%2B3%29....replace 5n with 2n%2B3n
n%5E2%2B2n%2B3n%2B6=+%28n%2B3%29

%28n%5E2%2B2n%29%2B%283n%2B6%29=+%28n%2B3%29

n%28n%2B2%29%2B3%28n%2B2%29=+%28n%2B3%29

%28n%2B3%29%28n%2B2%29=+%28n%2B3%29........divide both sides by n%2B3

%28n%2B3%29%28n%2B2%29%2F%28n%2B3%29=+%28n%2B3%29%2F%28n%2B3%29..reduce


%28n%2B2%29=+1
