1.	Factorize each of the following expressions:27x2 - 12y2
Answer» Consider 27x² - 12y²,Taking 3 common we get,3 [(3x)² – (2y)²] As we know a² - b² = (a-b) (a+b) = 3 (3x + 2y) (3x – 2y)

Answer»

Consider 27x² - 12y²,Taking 3 common we get,3 [(3x)² – (2y)²]

As we know a² - b² = (a-b) (a+b)

= 3 (3x + 2y) (3x – 2y)
