Answer:
HERE YOUR ANSWER
Step-by-step explanation:
5a-[a²-{2a(1-a+4a²)-3a(a²-5a-3)}]-8a
=5a-[a²-{2a-2a²+8a³-3a³+15a²+9a}]-8a
=5a-[a²-2a+2a²-8a³+3a³-15a²-9a]-8a
=5a-[-9a²-11a-5a³]-8a
=5a+9a²+11a+5a³-8a
=8a+9a²+5a³
i guess this is it. not entirely sure its correct SO SEE ANOTHER ONE I AM SURE IT IS CORRECT
OR
5a-[a²-{2a(1-a+4a²)-3a(a²-5a-3)}]-8a
=5a-a²+{2a(1-a+4a²)-3a(a²-5a-3)}-8a
=5a-a²+2a-2a²+8a³+15a²+9a-8a
=8a+12a²+5a³
IT IS CORRECT ANSWER
