Not sure about partial fraction decomposition

Question

I need to find the partial fraction decomposition of the expression with a denominator containing nonrepeating linear factors.

The given equation is 7x/x²-25

After doing some factoring I end up with A/(x-5) + B/(x+5)

I end up finding A=35/10 and B=35/10

After simplifying I end up with 3&1/2 over (x-5) + 3&1/2 over (x+5)

However, the math software is saying I am wrong. Did I miscalculate somewhere?

Answer 1

The third partial should be C / (x² - 5).
