Answer 2

Question:—

• Find the cube of the problem 3x-5y.

Answer:—

• 27x³-125y³-135x²y+225xy²

Solution:—

3x-5y

using formula :-

(a-b)³ = a³-b³-3ab(a-b)

here a = 3x

b = 5y

putting this values in the above formula

→ (3x-5y)³ = (3x)³ - (5y)³ -3(3x)(5y)(3x-5y)

→ 27x³-125y³-45xy(3x-5y)

→ 27x³-125y³- 135x²y+ 225xy²
