Issolvi (x-1)^2+(x-y)^2

$$( x - 1 ) ^ { 2 } + ( x - y ) ^ { 2 }$$

Evalwa

$$\left(x-y\right)^{2}+\left(x-1\right)^{2}$$

Passi tas-Soluzzjonijiet

Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(x-1\right)^{2}.

$$x^{2}-2x+1+\left(x-y\right)^{2}$$

Uża teorema binomjali \left(a-b\right)^{2}=a^{2}-2ab+b^{2} biex tespandi \left(x-y\right)^{2}.

$$x^{2}-2x+1+x^{2}-2xy+y^{2}$$

Ikkombina x^{2} u x^{2} biex tikseb 2x^{2}.

$$2x^{2}-2x+1-2xy+y^{2}$$
