Question

a-3b+a cube-27b cube factorize

Answer 1

Step-by-step explanation:

a-3b+a^3-27b^3

=a+a^3-3b-27b^3

=a(1+a^2)-3b(1+9b^2)

Answer 2

Answer:

$a - 3b + a {}^{3} - 27 \\ { a}^{3} - a - 3b - 27b \\ {a}^{3} - a - 30b \\ {a}^{3} - 6a - 5a - 30b \\ a ( {a}^{} - 6 ) + 5 (a - 6) \\ (a - 6) (a + 5)$
