Question

if x-1 = 15/4, then value of x+1/x is = ? (a). 17 (b). 4 (c). 17/4 (d). 19/4 please anybody answer it.​

Answer 1

Step-by-step explanation:

×+√15=4

x=4-√15

so putting x in x+1/x

4-√15+1/(4-√15)

above equation can also be written as

(4-√15)/1+1/(4-√15)

taking lcm of 1 & 4–√15

So lcm is 4-√15

((4-√15)²+1)/(4-√15)

(16+15–8√15+1)/(4-√15)

(32–8√15)/(4-√15)

Taking 8 common from numerator

8(4-√15)/(4-√15)

4-√15 is cancelled from numerator and denominator so

Ans= 8

I hope help you
