Factorize:
6xy – 4y + 6 – 9x

Given 6xy – 4y + 6 – 9x = (2y×3x – 2y×2 + 3×2 – 3×3x)

Taking 2y common from 1^st and 2^nd term and – 3 from 3^rd and 4^th,

6xy – 4y + 6 – 9x = 2y(3x – 2) + ( – 3)(3x – 2)

⇒ 6xy – 4y + 6 – 9x = (3x – 2) (2y – 3)

Factorize the following expressions :

2a⁵b³ – 14a²b² + 4a³b

Factorize:

2ab + 2b + 3a

Factorize:

2x + 3xy + 2y + 3y²

Factorize:

15b² – 3bx2 – 5b + x²
