Представьте в виде многочленов 1)(a-2)^3 2)(y+3)^3 3)(2y-3)^3 4)(3n-2m)^3

1)(a-2)^3=a^3-6*a^2+12*a-8
2)(y+3)^3=y^3+9*y^2+27*y+27
3)(2y-3)^3=8*y^3-36*y^2+54*y-27
4)(3n-2m)^3=27*n^3-54*m*n^2+36*m^2*n-8*m^3

(a-2)³=a³-6а²+12a-8
(y+3)³=y³+9y²+27y+27
(2y-3)³=8y³-3*3*2y*2y+3*2y*3*3-27=8y³-36y²+54y-27
(3n-2m)³=27n³-3*3n*3n*2m+3*3n*2m*2m-8m³=27n³-54mn²+36m²n-8m³
