Answer 2

To Find :- Factorise: 49a² – 36y² .

Solution :-

→ 49a² - 36y²

→ 7 × 7 × a × a - 6 × 6 × y × y

→ 7²a² - 6²y²

using a^m × b^m = (a × b)^m ,

→ (7a)² - (6y)²

now, using (a² - b²) = (a + b)(a - b),

→ (7a + 6y)(7a - 6y) (Ans.)

Therefore, factorise form of given expression is equal to (7a + 6y)(7a - 6y) .
