Factorize:
a² + a – 3a² - 3

We have,

At first we’ll take common from the expression

= a (a² + 1) – 3 (a² + 1)

= (a – 3) (a² + 1)

Hence,

The given expression can be factorized as:

Factorize:

(3a - 1)² – 6a + 2

Factorize:

(2x - 3)² – 8x + 12

Factorize:

3ax – 6ay – 8by + 4bx

Factorize:

abx² + a²x + b²x + ab
