Here, is Ur answer☻
》a+1/a = 6
(a+1/a ) ^2= 6 ^2 ( on squaring both sides)
a^2+1/a^2+2× a×1/a = 36
a^2+1/a^2+2= 36
a^2+ 1/2^2= 36-2
a^2+1/a^2 = 34
》( a-1/a)^2= a^2+1/a^2-2×a×1/a
(a-1/a)^2 = a^2+1/a^2 -2
(a-1/a)^2= 34- 2 ( a^2+1/a^2= 32)
(a-1/a)^2 = 32
(a-1/a)^2 = 32
a-1/a = +root 32
a-1/a = 4 root 2
》a+1/a = 6
(a+1/a ) ^2= 6 ^2 ( on squaring both sides)
a^2+1/a^2+2× a×1/a = 36
a^2+1/a^2+2= 36
a^2+ 1/2^2= 36-2
a^2+1/a^2 = 34
》( a-1/a)^2= a^2+1/a^2-2×a×1/a
(a-1/a)^2 = a^2+1/a^2 -2
(a-1/a)^2= 34- 2 ( a^2+1/a^2= 32)
(a-1/a)^2 = 32
(a-1/a)^2 = 32
a-1/a = +root 32
a-1/a = 4 root 2
Sorry wrong answer
it will be 4√2
