Please help
I am not getting it​

Answer 1

Step-by-step explanation:

X+1/x = 9-4√5 + 1/(9-4√5)

Rationalize the fraction by multiplying with (9+4√5)/(9+4√5)

After u multiply it will give 9-4√5 + (9+4√5)/1

Since its divided by one it won't make a difference

It will become 9-4√5+9+4√5

Simplify like terms

Answer will be 18
