Final answer:
To evaluate the expression 2a²(a³—a)—3a(a⁴+2a)—2(a⁴—3a²), you can use the steps to simplify the expression and combine like terms.
Step-by-step explanation:
To evaluate the expression 2a²(a³—a)—3a(a⁴+2a)—2(a⁴—3a²), we can simplify it step by step:
- Multiply the terms within parentheses:
- Expand any exponents:
- Combine like terms:
Using these steps, we can simplify the expression further:
- 2a²(a³—a) can be written as 2a^5 - 2a^3
- 3a(a⁴+2a) can be written as 3a^5 + 6a^2
- 2(a⁴—3a²) can be written as 2a^4 - 6a^2
Combining these simplified terms, we have:
2a^5 - 2a^3 - 3a^5 - 6a^2 + 2a^4 - 6a^2
Finally, combining like terms, the expression simplifies to:
-a^5 - 4a^4 - 12a^2
