Expand the following -» (3x - 2y )³

Given: Expression (3x - 2y)³

To find: Write the expression in expanded form?

Solution:

Using algebraic identity,

(a - b)³ = a³-b³-3ab(a - b)

Here, a=3x and b=2y

Substitute the values,

(3x-2y)³ = (3x)³ - (2y)³ -

3(3x) (2y) (3x-2y)

(3x - 2y)³ = 27x³ - 8y³ – 18xy(3x – 2y)

(3x-2y)³ = 27x³8y³54x²y+36xy²

Therefore, the expanded form is

(32 2y)³ = 27³-8y³-54x²y + 36ay²
