Best ResponseYou've already chosen the best response.4treat \((pq) =a\) and \((p+q)=b\), it's easier to look at these if they're letters instead of big, scary terms

Best ResponseYou've already chosen the best response.4\[(pq)(p+q)+(pq) \implies ab+a\] That means if we factor out the common term \(a\) we would have \[=a(b+1)\]
