we usually represent sqrt(-1) as i , but only a quadratic eqn or a eqn of high power would have led to represent the value as i.so for a quadratic eqn we obtain two values ,so why dont we have the two values as +i and -i.(adsbygoogle = window.adsbygoogle || []).push({});

statement 1:

X^2=4 so , X=+2 and -2

Statement 2:

X^2= -1 so X=+i and -i

is statement 2 possible or my question is wrong??

Have i asked a stupid q so that i should brush up my basics??
