If x square-4/x square=3 then x=​

Answer»

ANSWER:

x = under root 2 ✖ iota , iota = underroot - 1

Step-by-step explanation:

x2 - 4 /x2 =3

Cross multiplying,

x2 - 4 = 3x2

-4 = 3x2 - x2

-4 = 2x2

-4/2 = x2

-2 = x2

Taking under root on both SIDES,

Under root - 2 = x

x = under root 2 ✖ underroot - 1

As underroot - 1 = iota

x = under root 2 ✖ iota
