Answer:

see here is the ans mate hope this is helpful to you❣️

Answer 2

Answer:

This is a famous formula:

$\bigstar \framebox{ (a - b)^{3} = a^3-b^3-3ab(a-b) }$

(a−b)*(a−b)*(a−b)

=(a−b)(a²−2ab+b²)

=(a)(a²)+(a)(−2ab)+(a)(b²)+(−b)(a²)+(−b)(−2ab)+(−b)(b²)

=a³−2a²b+ab²−a²b+2ab²−b³

=a³−3a²b+3ab²−b³

=a³-b³-3ab(a-b)

$\huge \framebox{ HOPE THIS HELPS :D}$
