Put your x guys together and put your y's guys together. You need to be able to complete the square. Recall (m+n)^2=m^2+2mn+n^2 So if we have a^2+ja+k and we want to find what k is that completes the square: We divide j/2 then square that result. This will be k. k=(j/2)^2 So if we have a^2+ja+(j/2)^2 we can rewrite this as (a+j/2)^2 Or if we have m^2+2mn+? ?=(2n/2)^2=(n)^2=n^2 So m^2+2mn+n^2=(m+n)^2 like we said above.
