Answer 2

Step-by-step explanation:

Hey !! I am here to help you.

$81 {x}^{2} + 99x + 28 \\ 81 {x}^{2} + 63x + 36x + 28 \\ 9x(9x + 7) + 4(9x + 7) \\ (9x + 7)(9x + 4) \\ hence \: factorised.$

we applied mid term splitting in this question.

we splitted 99x as 63x and 36x.

we took 9x common in first two terms,

and took 4 common in another two terms.

then we took them together

and hence factorised..

HOPE IT HELPED YOU !!
