Hello Candice
When I look at your problem I see the following
(8x9+10x2+14x) /(143x)
Each term is divisible by 2x, so we can rewrite the problem like this.
2x(4x8+5x+7)
------------------
2x (142)7
The 2x in the numerator and denominator will cancel, leaving
4x8+5x+7x
---------------
(142)(7)
---------------
(142)(7)
Now, is it possible your original expressions has a typo and they exponent in the denominator should be on the x and not the 14? Below is the solution under that assumption.
8x9+10x2+14x)
------------------
14X3
------------------
14X3
We can still factor our a 2x
(2x)(4x8+5x+7)
------------------
(2x)(7X2)
------------------
(2x)(7X2)
And again the 2x in the numerator and denominator will cancel, leaving
4x8+5x+7
-------------
7X2
-------------
7X2
