Question

If x=3+√7/2 find the value of 4x^2+1/x^2

Answer 1

Answer:

$32$

Step-by-step explanation:

$x=\frac{3+\sqrt{7} }{2}$

∴$x^2=\frac{16+6\sqrt{7} }{4} =4+\frac{3\sqrt{7} }{2}$

$4*(4+\frac{3\sqrt{7} }{2} )+\frac{2}{8+3\sqrt{7} }$

$=16+6\sqrt{7} +2*(8-3\sqrt{7} )$

$=16+6\sqrt{7} +16-6\sqrt{7}$

$=32$

∴ $32$
