Question

If x≠0 and x+1/x =2 find x²+1/x²​

Answer 1

Answer:

If x≠0 and x+1/x =2 find x²+1/x² = 0

Answer 2

Answer:

2

Step-by-step explanation:

given (x+1/x)=2

to find :x^2+1/x^2    (^-power)  

we know formula (a+b)^2=a^2+b^2+2ab

here a=x,b=1/x applying the formula

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

we want x^2+1/x^2=(x+1/x)^2-2*(x)*(1/x)   x and 1/x got cancel on next step

                               =2^2-2*1  

                               =4-2=2
