4a²-9b²-(2a-3b)
(4a²-9b²)-(2a-3b)
[(2a)²-(3b)²]-(2a-3b)
a²-b² = (a+b)(a-b)
(2a-3b)(2a+3b) - (2a-3b)
taking (2a-3b) common
(2a-3b)(2a+3b-1)
a²+b²-2(ab-ac+bc)
a²+b²-2ab+2ac-2bc
(a²+b²-2ab) + (2ac-2bc)
a²+b²-2ab => (a-b)²
(a-b)² + 2c(a-b)
taking (a-b) common
(a-b)(a-b+2c)
hope this helps
any confusion then message me
