Answer 1

Answer:

Here ya go!

Step-by-step explanation:

x-2y+3z

Substituting the value os x,y, and z:

(2a²-a³+3a+4)- 2(2a³-3a²+2-2a)+3(a^4+3a³-6-5a²)

(-a³+2a²+3a+4)- (2a³-6a²+4-4a)+ (3a^4+9a³-15a²-18)

Here when removing from bracket bring the same numbers together!

3a^4-a³-2a³+9a³+2a²-6a²-15a²+3a-4a+4+4-18

3a^4+6a³-19a²-a-10
