Answer 2

Given:

(3x-5)³

To find:

Expanded form of the given expression.

Solution:

1) We can expand the given term by the direct formula of the algebra

(A-B)³ = A³-B³-3AB(A-B)

2) We have (3x-5)³

on comparing with the formula:

A = 3x

B = 5

(3x-5)³

(3x)³-5³-3×3x×5(3x-5)

27x³-125-45x(3x-5)

27x³-125-135x²+225x

So the expanded form of (3x-5)³ is 27x³-135x²+225x-125.
