What is 5-X divided by X²-25?

Answer 1

30

Answer 2

(5 -x ) / (x^(2) - 25)

Factor the denomiator

(5 - x) / ( x - 5)(x + 5)

Multiply by '-1'

-(5 - x) / (x - 5)(x + 5)

(-5 + x) / ( x - 5)(x + 5)

(x - 5)/(x - 5)(x + 5)

Cancel down by 'x - 5'

Hence

1 /( x + 5)

Answer 3

5 - x

_____

x2 - 25

You can divide the -25 by the 5 (to leave -5) and the x2 by the -x (to leave -x).

This results in:

1

_____

-x - 5
