\left(2x-2y\right)\left(x+y\right)-\left(x-y\right)^{2}
Uża l-propjetà distributtiva biex timmultiplika 2 b'x-y.
2x^{2}-2y^{2}-\left(x-y\right)^{2}
Uża l-propjetà distributtiva biex timmultiplika 2x-2y b'x+y u kkombina termini simili.
2x^{2}-2y^{2}-\left(x^{2}-2xy+y^{2}\right)
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(x-y\right)^{2}.
