Question

how can i find the solution of x-a= 1/x ?

Answer 1

cross multiply ==> x^2-ax-1=0, solve for x

Answer 2

u factor out an x than what?

Answer 3

to solve the quadratic equation , ot's better here to use the quadratic formula

Answer 4

so u would have x= a + - sqrt a^2 -4(x)(1)/ 2x?

Answer 5

for x^2-ax-1=0 ==> we got [-a + - sqrt(a^2-4*1*1)] / 2(1)

Answer 6

you put the coefficient of x^2 and coeffcient of x

Answer 7

Ohhh yaaa so you would get -a +- sqrt a^2 +4/2

Answer 8

than -a +- a+2/2 ?

Answer 9

[-a + - sqrt(a^2+4)] / 2 , exactly

Answer 10

thanks a lot:)

Answer 11

any time
