4x² - 9y² - 2x - 3y = (2x + 3y) ( 2x - 3y -1)

Step-by-step explanation:

4 x square minus 9 Y squared minus 2 x minus 3 y factorise

4x² - 9y² - 2x - 3y

= (2x)² - (3y)² -(2x + 3y)

using identity a² - b² = ( a+b)(a -b)

a = 2x & b = 3y

= (2x + 3y)(2x - 3y) - (2x + 3y)

Taking (2x + 3y) common

= (2x + 3y) ( 2x - 3y -1)

4x² - 9y² - 2x - 3y = (2x + 3y) ( 2x - 3y -1)
