15\left(4x^{2}-12xy+9y^{2}\right)-4\left(4x-6y\right)-16
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(2x-3y\right)^{2}.
60x^{2}-180xy+135y^{2}-4\left(4x-6y\right)-16
Uża l-propjetà distributtiva biex timmultiplika 15 b'4x^{2}-12xy+9y^{2}.
60x^{2}-180xy+135y^{2}-16x+24y-16
Uża l-propjetà distributtiva biex timmultiplika -4 b'4x-6y.
