4(ab + 1)² - 9(a - 1)²
= {2(ab + 1) }² - {3(a - 1)}²
= (2ab + 2 )² - (3a - 3)²
use formula, x² - y² = (x - y)(x + y)
= (2ab +2 + 3a - 3)(2ab +2 -3a + 3)
= (2ab +3a - 1)(2ab -3a +5)
= {2(ab + 1) }² - {3(a - 1)}²
= (2ab + 2 )² - (3a - 3)²
use formula, x² - y² = (x - y)(x + y)
= (2ab +2 + 3a - 3)(2ab +2 -3a + 3)
= (2ab +3a - 1)(2ab -3a +5)
