Question

x square -3x +1 =0 find x square +1 by x square​

Answer 1

Answer:18+6$\sqrt{5$/6+2$\sqrt{5$

Step-by-step explanation:

$x^{2}$-3x+1=0

x=-b+-$\sqrt{b^{2} -4ac$/2a

= -(-3)+-$\sqrt{3^{2} -4*1*1$/2*1

=3+-$\sqrt{5$/2

x= 3+$\sqrt{5$/2          x=3-$\sqrt{5$/2

$x^{2}$+1/$x^{2}$

(3+$\sqrt{5$/2)^2+1/3+$\sqrt{5$/2

=(18+6$\sqrt{5$)/(6+2$\sqrt{5$)

you can rationalize futher.............
