I studied somewhere that √4=2. THEN how can x=2 as well as -2

What is the value of X when x²+1/x²+x-1/X =4

[hindu]

Mam when we say x2 =0.2 it is written in book as square root 0.2 only with no negative sign. Plz clear my doubt

This is a wrong way yo look at of a square root is always positive....u will learn this when u come to 11th or 12th...also, it's supposed to be solved like x2-4=0...therefore x+2.x-2=0, and then we get x=+-2...value of square root of four is always zero.
