a^{2}+2ab+b^{2}-b\left(2a+b\right)
Uża teorema binomjali \left(p+q\right)^{2}=p^{2}+2pq+q^{2} biex tespandi \left(a+b\right)^{2}.
a^{2}+2ab+b^{2}-\left(2ba+b^{2}\right)
Uża l-propjetà distributtiva biex timmultiplika b b'2a+b.
a^{2}+2ab+b^{2}-2ba-b^{2}
Biex issib l-oppost ta' 2ba+b^{2}, sib l-oppost ta' kull terminu.
a^{2}+b^{2}-b^{2}
Ikkombina 2ab u -2ba biex tikseb 0.
