Question

plz I need very urgent​

Answer 1

Step-by-step explanation:

X + 1/x = 3…(i)

We know ,

(X+1/x)^2 = x^2 + (1/x)^2 + 2(x * 1/x)

=> (X+1/x)^2 = x^2 + (1/x)^2 + 2

Substituting value from (i)

(3)^2 = x^2+(1/x)^2+2

= 9–2 = x^2+(1/x)^2

Ans. X^2 + (1/x)^2 = 7.

Answer 2

Answer:

X^2+(1/x)^2

Step-by-step explanation:

x+1/x=3....(i)

we know, (x+1/x)^2=(1/x)^2+2(x*1/x)

=>(x+1/x)^2=x^2+(1/x)^2+2

substituting value from (i) (3)^2=x^2+(1/x)^2+2

=>9-2 = (1/x)^2

ans. x^2+(1/x)^2=7

i hope it may help you
