answer this question​

Answer 1

Answer:

$3( {a - 2b)}^{2} - 5(a - 2b) \\ \\ 3( {a}^{2} \: - 4ab + 4 {b}^{2} ) - 5a \: + 10b \\ \\ 3 {a}^{2} - 12ab + 12 {b}^{2} - 5a + 10b$

or elss

take common

$3( {a - 2b)}^{2} - 5(a - 2b) \\ \\ take \: (a - 2b) \\ \\ (a - 2b)(3(a - 2b) - 5) \\ \\ (a - 2b)(3a - 6b - 5)$
