Разложите на множители: m^3+27; y^3+1/8; 8+c^3; 8/27+z^3; 1-x^3; b^3-1/125; -x^3+y^3; 1/27-t^3; . help !

M³+27=(m+3)(m²-3m+9)
y³+1/8=(y+1/2)(y²-1/2y+1/4)
8+c³=(2+c)(4-2c+c²)
8/27+z³=(2/3+z)(4/9-2/3z+z²)
1-x³=(1-x)(1+x+x²)
b³-1/125=(b-1/5)(b²+1/5+1/25)
y³-x³=(y-x)(y²+xy+x²)
1/27-t³=(1/3-t)(1/9+1/3t+t²)
