Question

Solve the equation (eqn coming soon)
.
.
ANSWER = {-1,5 pm 2 sqrt6

Answer 1

\[(x-\frac{ 1 }{ x })^2-8(x+\frac{ 1 }{x })-16=0\]

Answer 2

i have solved this and i am getting 2 values of y

Answer 3

\[y=4+4\sqrt{2}, y=4-4\sqrt{2}\]

Answer 4

have u written (x-1/x)^2 as (x+1/x)^2 -4 ?
and then put y= x+1/x

Answer 5

yes i have done it all

Answer 6

then u should get y =10 or -2

Answer 7

i asked a question like this hours ago right

Answer 8

yes. and i have helped u solve..... why u not getting y = 10,-2 ??

Answer 9

y^2-8y-16=0 this is the quadratic

Answer 10

\(\huge (x-1/x)^2 as (x+1/x)^2 -4\)

Answer 11

u forgot -4

Answer 12

y^2-8y-20=0 is'nt it

Answer 13

yes.
y=?

Answer 14

y=10 and y=-2

Answer 15

yesm now put y=x+1/x

Answer 16

10=x+1/x right?

Answer 17

yes, solve that quadratic.....

Answer 18

done

Answer 19

\[x=5\pm 4\sqrt{6} and x=-1\]
