If x2 + 1/ x2 = 66 what is x- 1/x

( x - 1/x )^2

= x^2 + 1/x^2 - 2

= 66 -2

= √64

8

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
