Answer:
(4a3-5a-3)(2a2-7a+3)
Step-by-step explanation:
use 4a3 to multiply everything in the both brackets=
8a⁵-28a⁴+12a³. then use -5a to multiply everthing in the both brackets =
8a⁵-28a⁴+12a³-10a³+35a²-15a. then use -3a to multiply everthing in the both brackets =
8a⁵-28a⁴+12a³-10a²+35a²-15a-6a²-21a-9.then you furthermore solve=
8a⁵-28a⁴+2a³+29a²-36a-9
