Question

Разложите на множители. 15x3-15y3= 3x2-6xy+3y2= x-3x2+x3-3=

Answer 1

15x³ -15y³ =15(x³-y³)=15(x-y)(x²+xy+y²) 3x² -6xy+3y² =3(x²-2xy+y²)=3(x-y)² x-3x² +x³ -3=(x-3)+x²(x-3)=(x-3)(1+x²)

Answer 2

15(х^3-у^3)=15(х-у)(х^2+ху+у^2) 3(х^2-2ху+у^2)=3(х-у)^2 (х-3)+(х^3-3х^2)=(х-3)+х^2(х-3)=(х-3)(х^2+1)
