Answer 2

Explanation:

Given Factorise the following expressions..

9x^2 - 1/16y^2

• We need to factorise the given expression.
• This is in the form of a^2 – b^2 = (a + b)(a – b)
• We know that a^2 – b^2 = (a + b)(a – b)  
• By factorising 9x^2 – 1/16 y^2 we get
• This can be written as (3x)^2 – (1/4y)^2
• Now this will be (3x + 1/4y)(3x – 1/4y)
