Expand: (3x + 4y)(3x - 4y)

Factorise the following algebraic expression by using the identity a² – b² = (a + b)(a – b)

9 – 4y²

Simplify (5x – 3y)² – (5x + 3y)²

The value of p for 51² – 49² = 100p is 2.

Factorise the following using the identity a² – b² = (a + b)(a – b).

4x² – 49y²

Factorise the following using the identity a² – b² = (a + b)(a – b).

`(4x^2)/9 - (9y^2)/16`

Factorise the following using the identity a² – b² = (a + b)(a – b).

x⁴ – y⁴

Factorise the expression and divide them as directed:

(9x² – 4) ÷ (3x + 2)

The sum of first n natural numbers is given by the expression `n^2/2 + n/2`. Factorise this expression.
