Question

my question is square 3 minus one upon square 3 + 1 please give me the answer it is a rational number

Answer 1

$\frac{ \sqrt{3} - 1 }{ \sqrt{3} + 1 } = \frac{ \sqrt{3} - 1}{ \: \sqrt{3} + 1 } \frac{ \: \sqrt{3} - 1\: }{ \: \sqrt{3} - 1 \: } = \frac{3 + 1 - 2 \sqrt{3} }{2}$


Cancelling '2' from Numerator and Denom.
Desired Rationalization =
$2 - \sqrt{3}$
