(3b - 4a) (3b - 4a) is the same as (3b - 4a)²

Ang tawag sa factor na yan ay square of binomial.  And product naman ng square of binomial ay perfect square trinomial.  
(Tandaan mo yan dahil lalabas yan sa exam mo.)

Para ba makuha ang product ng square of binomial?  Mayroon pattern na dapat mo lang sundin:

Pattern 1: (a + b)² = a² + 2(a)(b) + b²
Pattern 2: (a - b)² = a² - 2(a)(b) + b²

Gamitin natin ang pattern 2:
(a - b)² = a² - 2(a)(b) + b²

(3b - 4a)² = (3b)² - 2(3b)(4a) + (4a)²
                = 9b² - 24ab + 16a²   or  16a² - 24ab + 9b²
