Factorize:4x2 – 9y2 – 2x – 3y

We have,We can also write this as:= (4x)2 –(9y)2 – ( 2x + 3y)Now,Using identity: a2 - b2 = (a – b)(a + b)

Factorize:
4x² – 9y² – 2x – 3y

We have,

We can also write this as:

= (4x)² –(9y)² – ( 2x + 3y)

Now,

Using identity: a² - b² = (a – b)(a + b)

Factorize:

9a² + 3a – 8b – 64b⁴

Factorize:

x² – y² + 6y – 9

Factorize:

x⁴ – 1

Factorize:

a – b – a² + b²
