Question

if (x-1/x) = 5 then what is (x+1/x)​

Answer 1

Step-by-step explanation:

(x-1/x)²+4.x.1/x

=(5)²+4

=25+4=29

x+1/x=√29

Answer 2

Lets find x value

GIVEN [x-1/x]=5

         ⇒x-1 =5x

         ⇒-1 =5x-x

         ⇒-1 =4x

        ⇒x=-1/4

now put x value in the above equation i.e.,[x+1/x]

⇒-1/4+1/[-1/4]

⇒-1/4+[-4/1]

⇒-1/4-[4×4]/[1×4]      {we are equating denominators for that we are multiplying with 4}

⇒-1/4-16/4

⇒-17/4

hopefully !!this helps u!!!
