Simplify the rational expression x-2/x2+3x-10

The answer is 1/x+5.

To get this:
    x - 2          ⇒     x - 2      
x² + 3x - 10    (x - 2)(x + 5)
Cancel out any repeating factors. In this case, we have (x - 2);
     x - 2         ⇒       1
(x - 2)(x + 5)         x + 5

Hope this helps.
                            

I’m pretty sure it’s i think : /

The first one is 2/3the second is 1/160the third is 4/125
