❄❄❄ INTRODUCTION ❄❄❄

✔ Factorization is the reverse process of multiplication.

✔ The process of finding two or more expressions whose product is the given expression is called factorization.

✔ Example 1 : 4x²-25 = (2x+5)(2x-5)

✔ Example 2 : 6y²-y-15 = (2y+3) (3y-5)

The actual question is :

27x³ + 125y³

==================================

❄❄❄❄ SOLUTION ❄❄❄❄

27x³+125y³

= (3x)³+(5y)³

= (3x+5y) {(3x)²-3x(5y) + (5y)²}

= (3x+5y) (9x²-15xy+25y²)

Answer 2

Hi there!

Correct question : 27x³ + 125y³

Factorisation using the formula

a³+b³ = (a+b) (a²-ab+b²)

(3x)³ + (5y)³ = ( 3x + 5y ) ( 9x² - 15xy + 25y² )
