Question

if x +1/x-17/4 than find the value of x​

Answer 1

Answer:

Hello,

Step-by-step explanation:

x+1/x =17/4

Square on both sides,

(x+1/x)²=(17/4)²

x²+1/x² +2= (289/16)

x²+1/x² =289/16 -2

x² +1/x² = (289-32)/16

x² +1/x² =257/16

Now,

Subtract 2(x*1/x) from both sides,

x²+1/x² -2 =(257/16) -2

______________________

By formula (a-b)²=a²+b² -2ab

______________________

(x-1/x)² =(257-32)/16

(x-1/x)² = 225/16

(x-1/x)² =(15/4)²

x-1/x =15/4

I hope this will help you
