---------------------------------------------------

Rules-
============
+ + GIVES - -

- + GIVES + +

+ - GIVES - +

- - GIVES + -

for example

6x^2 + x -1= 0

8y^2 +10y + 3 = 0

See the sign used in 1st equation i.e + and -

From above table + - gives - +

So x value will be in - and +

Now simliarly 2 nd equation has sign + and +

From table we get + + gives - -

So value of y will be in - and -

Therefore x is greater equal y

2nd rule

If ques comes

X^2 = xyx(any value)

Y^2 = xyz

Ans will be cant be determined

3rd rule

If comes

X^2 = xyz

Then value of x will be in + and -

Y= under root of xyz

value of y will be always +

So ans will be x smaller equal y
