Answer 2

Answer:

(a-12b) (a-3b)

Step-by-step explanation:

$a^{2}$ - 15ab + 36$b^{2}$                              

$a^{2}$  ×  36$b^{2}$ =     36$a^{2} b^{2}$

(- 12ab) +  (- 3ab)   =  (-15ab)

(- 12ab)  ×  (- 3ab)   =      36$a^{2} b^{2}$

$a^{2}$ - 12ab - 3ab +   36$a^{2} b^{2}$

a (a -12b) -3 (a-12b)

(a-12b) (a-3b)
