Question

help me in this question of maths

Answer 1

$\frac{2 \sqrt{5 } + 3}{2 \sqrt{5} - 3} + \frac{2 \sqrt{5} - 3 }{2 \sqrt{5} + 3 }$
$\frac{(2 \sqrt{5} + 3) ^{2} + {(2 \sqrt{5} - 3) }^{2} }{ {(2 \sqrt{5})}^{2} - {(3)}^{2} }$
$\frac{20 + 9 + 12 \sqrt{5} + 20 + 9 - 12 \sqrt{5} }{20 - 9}$
$\frac{40 + 18}{11}$
$\frac{58}{11}$
As a+b√5=(58/11)
a=58/11
and b=0
That's all
