Factorised form of 4y² - 12y + 9 is ________

Solution:

Factorised form of 4y² - 12y + 9 is (2y - 3)².

Given, 4y² - 12y + 9

= 4y² - 6y - 6y + 9

= 2y (2y - 3) - 3 (2y - 3)

= (2y - 3) (2y - 3)

= (2y - 3)²

Factorired form of 25x² + 30xy + 9y² = (5x + 3y)²

Given,25x² + 30xy + 9y²

=  25x² + 15xy + 15 xy + 9y²

= 5x(5x + 3y) + 3y(5x + 3y)

=(5x + 3y)(5x + 3y)

= (5x + 3y)²
