Answer:

divisor- 2a - 3  

dividend     -                             8a3  -  8a2        -  9  

divisor  * 4a2  -                         8a3  -  12a2          

remainder                                              4a2   -  9  

- divisor  * 2a    -                                    4a2  -  6a    

remainder                                                          6a  -  9  

- divisor  * 3   -                                                   6a  -  9  

remainder                                                                  0

Quotient :  4a2+2a+3  Remainder:  0

❣️\textbf{\underline{\red{\large{Step by step Explanation:-}}}}

\mathtt{40a^{4}-40a^{3}-45a}

\mathtt{\implies{5a(8a^{3}-8a^{2}-9)}}

\mathtt{\implies{5a(8a^{3}-12a^{2}+4a^{2}-6a+6a-9)}}

\mathtt{\implies{5a(4a^{2}(2a-3)+2a(2a-3)+3(2a-3))}}

\mathtt{\implies{(5a)(2a-3)(4a^{2}+2a+3)}}
