Answer:
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)
