To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above:
<span>7/x^2-3x - 1/x^2-9
</span>
2. When you factor the denominator, you obtain:
<span>7/x(x-3) - 1/(x+3)(x-3)
3. By simplifying the expression, you obtain:
3(2x+7)/x(x+3)(x-3)
</span> 3(2x+7)/x(x^2-9)
The answer is: 3(2x+7)/x(x^2-9)
To convert a mixed fraction into a first you need to convert it into an improper fraction.
To do that multiple 87 to 25 and then add 24
If you do that you will get 2199/25
then divide the numerator by the denominator.
87.96 is what you will get if you divdie it correctly
