Question 165857
Factor:
{{{u^2-v^2-2u-2v}}} Group the terms as shown:
{{{highlight((u^2-v^2))-highlight((2u+2v))}}} Factor the first binomial and factor 2 from the second binomial:
{{{highlight((u+v)(u-v))-highlight(2(u+v))}}} Now you can factor the common factor of {{{(u+v)}}} to leave you with:
{{{highlight((u+v)((u-v)-2))}}}
