I am not gonna go with that boring approach; let's try to be logical.
OK, what is \((a + b)^2\)?
1, x2+2.x.1+1^2= (x+1)^2
@tanvirms You really shouldn't answer... please.
Answering questions has a very bad impact.
well i answered cuz he wanted an answer :)
Dang, no! Don't ever give anyone the answer. Help them by leading them to an answer and explaining.
@Luis_Rivera I take it that you meant\[x^2 + 2x + \left(2\over 2\right)^2 = x^2 + 2x + 1 \]
