Step-by-step explanation:
5a-(2a² (2a(1-a+4a²)-(3a(a² -5a-3)))-8a
5a-(2a²(2a-2a²+8a²-3a(a²-5a-3))-8a
5a-2a²(2a- 2a²+8a³-3a(a²-5a-3))+8a
13a-2a²(2a-2a²+8a³-3a(a²-5a-3)+8a
13a-2a²(2a-2a²+8a³-3a(a²-5a-3))
13a-2a²(2a-2a²+8a³-3a³+15a²+9a)
13a-2a²(2a-2a²+5a³+15a²+9a)
13a-2a²(2a+13a²+5a³+9a)
13a-2a²(11a+13a²+5a³)
=13a-22a³-26a⁴-10a⁵
please follow me and give me brilliant mark.
