Question

Find the num
The sum of a number and its reciprocal 10/3. find the number 5​

Answer 1

x=3 or x= 1/3

Explanation:

Let the number = x

The reciprocal of the number = 1/x

According to the given statement:

x+1/x=10/3

x²+1/x=10/3

3(x²+1)=10x

3x²+3=10x

Move 10x to the L.H.S

3x²-10x+3=0

Break the middle term:

3x²-9x-x+3=0

3x(x-3)-1(x-3)=0

(x-3)(3x-1)=0

x-3=0 , 3x-1=0

x=0+3 , 3x=0+1

x=3 , 3x=1

x=3 ,x = 1/3

So x=3 or x= 1/3 ....
