Question

simplofy the factor (3a-2b) ³​

Answer 1

Answer :

27a^3-8b^b-18a^2b-12ab^2

Answer 2

Answer:

9a² - 12ab + 12ab² - 8b³

Step-by-step explanation:

(3a - 2b) is also (3a - 2b)(3a - 2b)(3a - 2b)

Solve the first two bracket = (3a - 2b)(3a - 2b) spilt

3a(3a - 2b) -2b(3a - 2b)

=9a² - 6ab - 6ab + 4b²

=9a² - 12ab + 4b²(3a - 2b) - (inserting third bracket)

=9a² - 12ab + 12ab² - 8b³ (ans). Goodluck.
