1)(х^6-3x+9)(x^3+3)
2)(n +1/2)(n^2-1/4n+1/4)
3)(1/2a-1/3b)(1/4a^2+1/6ab+1/9b^2)
4)(1/4y^2+yz+4z^2)(1/2y-2z)
5)(3/4x^4-2/3y^2)(9/16x^8+1/2x^4y^2+4/9y^4)
6)(25/36a^6-a^3b^3+36/25b^6)(5/6a^3+6/5b^3)

Answer 1

$a) x^9+27\ b) n^3+ frac{1}{8} \ c) frac{1}{8a^3} - frac{1}{27b^3} \ d) frac{1}{8y^3}- 8z^3\ e) frac{27}{64x^{12}} - frac{8}{27y^6} \ f) frac{125}{316a^9} + frac{316}{125b^9}$
