try multiplying (x+1) and (2x+1) out (x+1)(2x+1) 2x^2+2x+1x+1 2x^2+(2+1)x+1 look at the b term notice in your question that is your b=m+n what happens in our example if you multiply the m and n?

have you notice that b has been written as m+n that is your 3 has been written as 2+1 (do you notice this?)
