Question

Q5. Factorise: 125x ^ 3 + 1/(27y ^ 3)​

Answer 1

EXPLANATION.

Factorizes.

⇒ 125x³ + 1/27y³.

As we know that,

⇒ (5x)³ + 1/(3y)³.

As we know that,

Formula of :

⇒ (x³ + y³) = (x + y)(x² - xy + y²).

Using this formula in the equation, we get.

⇒ (5x + 1/3y)[(5x)² - (5x)(1/3y) + (1/3y)²].

⇒ (5x + 1/3y)[25x² - 5x/3y + 1/9y²].
