Question

разложите на множители 1)m^3+n^3
2)x^9-y^6
3)a^6-8
4)b^9+27

Answer 1

1)m^3+n^3=(m+n)(m^2-mn+n^2)
2)x^9-y^6=(x^3-y^2)(x^6+x^3y^2+y^4)
3)a^6-8=(a^2-2)(a^4+2a^2+4)
4)b^9+27=(a^3+3)(a^6-3a^3+9)

Answer 2

1) m³+n³=(m+n)(m²-mn+n²)
2) x^9-y^6=(x³-y²)(x^6+x³y²+y^4)
3) a6-8=(a²-2)(a^4+2a²+4)
4) b9+27=(b³+3)(b^6+3b³+9)
