What is the simplified form of the equation (x-1/x-1) x+5/x+1 -x-2/x-1(x+1/x+1)
1 answer:
Answer:
(We already know that: x -1/x-1 = 1 and x + 1/x + 1 = 1 there is no need of keeping them)
(x-1/x-1) x+5/x+1 -x-2/x-1(x+1/x+1)
= x + 5/x + 1 - x - 2/x - 1
= x²/x + 5/x + x/x - x²/x - 2/x - x/x
= x² + 5 + x - x² - 2 - x
= 5 -2
= 3
