Question

x(3-2/x)=3/x,findx²+1/x²=?

Answer 1

Answer:

Step-by-step explanation:

Hi ,

Let p( x ) = k² x² - 2kx - 3

If ( x + 1 ) is a factor p( x ) then

Remainder p ( - 1 ) = 0

k² ( - 1 )² - 2 k ( - 1 ) - 3 = 0

k² + 2k - 3 = 0

k² - k + 3k - 3 = 0

k ( k - 1 ) + 3 ( k - 1 ) = 0

( k - 1 ) ( k + 3 ) = 0

k - 1 = 0 or k + 3 = 0

k = 1 or k = - 3

I hope this helps you.
