Question

Hey guys !! Please tell the answer of this question !!

Factorise : a³-8b³

Ps. This is very urgent ​

Answer 1

Answer:

(a- 2b)(a²+4b²+2ab

Step-by-step explanation:

apply the identity [a³-b³= (a-b)(a²+b²+ab)

Answer 2

Answer:

(a - 2b) (a^2 + 2ab + 4b^2)

Step-by-step explanation:

Apply exponent rules:

==> a^3 - (2b)^3

Apply Difference of Cubes formula: x^3 - y^3 = (x - y)(x^2 + xy + y^2)

(a - 2b) (a^2 + a*2b + (2b)^2)

After simplifying:

==> (a - 2b) (a^2 + 2ab + 4b^2)
