Question

If x= 3 + V 8, find x2+ (1/x2) who will give right ans will got BRAINLIEST​

Answer 1

Answer:

x=3+v3 x2=(3=v8)2 = 9+8+6 v8=17+6 v8

x2+1/x2 = (3+v8)2+1/(3+v8)2

17+6 v18 + 1/17+6 v8

(17+6 v8)2+1/17+6 v8 X (17-6 v8)/(17-6 v8)

(17+6 v8)2(17-6 v8)+(17-6 v8)/289-288

(289-288)(17+6 v8)+17-6 v8

17+6 v8+17-6 v8=34
