Question

x+1/x=5 then find value of x.​

Answer 1

Answer:

$x + \frac{1}{x} = 5 \\ {x}^{2} - 5x + 1 = 0 \\ x = \frac{ - b + - \sqrt{ {b}^{2} - 4c} }{2a}$

you can us ethat formula

Answer 2

x+1 =5

x

x²+1 = 5

x

x²+1=5x

x²-5x+1=0

Discriminant d

=√b²-4ac

=√25-2(1)(1)

=√25-2

=√23

Using quadratic formula,

x= -b +- d

2a

= -(-5) +- √23

2(1)

= 5 + √23. or 5 - √23
