16x^{2}-40xy+25y^{2}-8x\left(2x-5y\right)
Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(4x-5y\right)^{2}.
16x^{2}-40xy+25y^{2}-16x^{2}+40xy
Uża l-propjetà distributtiva biex timmultiplika -8x b'2x-5y.
-40xy+25y^{2}+40xy
Ikkombina 16x^{2} u -16x^{2} biex tikseb 0.
25y^{2}
Ikkombina -40xy u 40xy biex tikseb 0.
