Помогите прошуРазложите на множители2) у^3-b^3; 4) m^3+R^3;6)64+s^3;8)1000+y^3;
2)y^3 - b^3 = (y-b)*(y^2 + by + b^2)
4)m^3 + R^3 = (m+R)*(m^2 - mR + r^2)
6)64 + s^3 = 4^3 + s^3 = (4 + s)*(16 - 4s + s^2)
8)1000 + y^3 = 10^3 + y^3 = (10 + y)*(100 - 10y + y^2)
2) y^3-b^3=(y-b)(y^2+yb+b^2) =(y-b)(y^2+by+b^2) 4) m^3+R^3=(m+R) (m^2-mR+R^2) 6) 64+s^3=4^3+s^3=(4+s) (4^2-4s+s^2) 8) 1000+y^3=10^3+y^3=(10+y) (10^2-10y+y^2)=(10+y) (100-10y+y^2)
