Answer 1

Answer:

$1.first \: we \: factorise =$

$12a = 2 \times 2 \times 3 \\ 15 = 3 \times 5 \\ we \: have \: to \: \: find \: the \: \\ common \: no. \\ that \: is \: = 3 =$

$so \: the \: answer \: will \: be \: \\ 3(4a - 5)$

$2. \: as \: i \: had \: explain \: before \\ we \: will \: find \: common \: \\ multiple \\ {9a}^{2} = 3 \times 3 \\ 24a = 3 \times 8 \\ common \: no.is \: 3$

$now \: answer \: \: will \: be \: \\ 3(3 {a}^{2} + 8a) \\ \\ hope \: it \: helps \: you$
