Answer 1

Answer:

(3a - 6b - 5)(a - 2b)

Step-by-step explanation:

Given Equation is 3(a - 2b)² - 5(a -2b)

Take the common factor : a - 2b.

⇒ (a - 2b[3(a - 2b) - 5]

⇒ (a - 2b)[3a - 6b - 5]

Hope it helps!

Answer 2

Answer:

$\boxed{(a-2b)(3a-6b-5)}$

Step-by-step explanation:

$3(a-2b)^2-5(a-2b)$

Take a - 2 b as common .............

$(a-2b)[3(a-2b)-5]$

$\implies (a-2b)[3a - 6b-5]$

$\implies (a-2b)(3a-6b-5)$
