That's very clever! I would have just

**solved**to see that the only x that satisfy that equation are and , then put those into P to see how I could cancel that irrational " " part. But Ruun's hint is much simpler. - March 30th 2013, 02:00 AMpaulianaRe: look for the value that satisfies the equation
I'm trying to solve it to but I don't get the equation. should I substitute the given?
