How to factor 18a2+6a5-8a3
Zielflug [23.3K]

Answer:

2a^2(3a^3-4a+9)

Step-by-step explanation:

You could change the equation to this: 6a^3a^2-8a^1a^2+18a^2

*This is the exact same as 18a^2+6a^5-8a^3

You can continue to break this down until you get:

2*3a^3a^2-2*4a^1a^2+2*9a^2

*This too = 18a^2+6a^5-8a^3

With this new equation, you can cancel out the common term: 2a^2

You come up with my answer.

<em>Hope this helps!!</em>
