Functions proof

[livid kite]

How can I prove this without cross multiplying and keeping the right hand side the same.

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

yes

@livid kite u want a hint right

[livid kite]

yea

just plug in $\sqrt{x}$ instead of $f(x)$ and plug in 1 instead of $f(1)$ because $\sqrt{1} = 1$

Now, if u open this its basically a hint that automatically gives u a solution: ||factor x-1 as a difference of squares.||
