Answer 1

Answer: 6

I hope it will help you

Answer 2

Answer:

just rationalize the denominator and you will get the ans

you can also directly put the value of x and y (after rationalizing) in the equation x2+y2+xy .

.....hope this helps..☺

So lets begin...

To find : The value of x^2 + y^2 + xy = 35

Given : x= \fraction {\sqrt2+1}{\squareroot2-1} and y=\fraction{\squareroot2-1}{\squareroot2+1}

To find : The value of x^2+y^2+xy

Solution :

First we solve the value of x and y be rationalizing,

The value of x,

then we rationalize y,

then substitute the value of x and y in the expression
