Question

Разложите на множители:
1) a^9-b^3
2) a^6-b^6
3) x^6-729
4) 64-y^6

Answer 1

1.

$a {}^{9} - b {}^{3} = (a {}^{3} - b) \times (a {}^{6} + a {}^{3} b + b {}^{2} )$

2.

$a {}^{6} - b {}^{6} = (a - b) \times (a {}^{2} + ab + b {}^{2} ) + (a + b) \times (a {}^{2} - ab + b {}^{2} )$

3.

$x {}^{6} - 729 = (x - 3) \times (x {}^{2} + 3x + 9) \times (x + 3) \times (x {}^{2} - 3x + 9)$

4.

$64 - y {}^{6} = (2 - y) \times (4 + 2y + y {}^{2} ) \times (2 + y) \times (4 - 2y + y {}^{2} )$

Надеюсь помогла :)
