Could someone please explain the best way to reduce these expressions?
4x^2
-----
2x^9
-2x-8
-----
x^2+2x-8
And how to solve this
x^2 = 14x
Thanks

When you divide powers you subtract the exponents. Of course, 4/2=2.
2-9=-7. So you have:
-2x-8
-----
x^2+2x-8
Always check to see if anything factors.
Now, cancel what will cancel.
And how to solve this
x^2 = 14x
There isn't much to this.
Divide through by x:
x=14 or 0.
