How do you do this? need it by tonight

Substitute "E" For X

First step:
When you divide, you subtract the exponents.
So first divide 9/3=3

**Then the smallest exponent number will be subtracted by the biggest exponent number. So x to the power of 2 subtract by x (when a variable is alone with no exponent, that means the exponent is 1).

Second step:
x to the power of 2 subtracted by x gives x, because 2-1 is 1 so you just put x.

Third step:
In division, + divided with - gives you a negative(-) answer.

Fourth step:
4/2 = 2

So the final answer is:
3x-2

Hope this helped!
