Answer:
[tex]2a^2(3a^3-4a+9)[/tex]
Step-by-step explanation:
You could change the equation to this: [tex]6a^3a^2-8a^1a^2+18a^2[/tex]
*This is the exact same as [tex]18a^2+6a^5-8a^3[/tex]
You can continue to break this down until you get:
[tex]2*3a^3a^2-2*4a^1a^2+2*9a^2[/tex]
*This too = [tex]18a^2+6a^5-8a^3[/tex]
With this new equation, you can cancel out the common term: [tex]2a^2[/tex]
You come up with my answer.
Hope this helps!!
