Question no.35 $x = c \sqrt{b} +4, find x +1/x$

Answer 1

X= c√b+4 X+1/X = c√b+4+1/c√b+4 X+1/X= (c√b+4/c√b+4)+{1/c√b+4*c√b-4/c√b-4} X+1/X= 1+{c√b-4/(c^2*b)-4^2} X+1/X = 1+c√b-4/c^2*b-16 X+1/X=( c^2*b-16/c^2*b-16)+(c√b-4/c^2*b-16) X+1/X = c^2*b-16+c√b-4/c^2*b-16 X+1/X = c^2*b+c√b-20/c^2* Hope my answer is correct.
