I think this may be simple, but I just cant seem to get it. So Ive decided to sign up to this site. Help please! if x^2+4x+p=(x+q)^2 +1 then the values of p and q are...? Thanks!

Expand the right hand side and equate coefficients of powers of x and constant terms: 4 = 2q p = q^2 + 1 Solve the above two equations for p and q.
