Question

Determine the nature of the roots for the following equation.

1/x - 1/x + 1 = 1/5

Answer 1

1/x - 1/(x + 1) = 1/5 ???

Answer 2

1 over x - 1 over x + 1 = 1 over 5 (:

Answer 3

5(x+1 - x) = x(x+1)
=> 5 = x^2+x
=> x^2+x-5 = 0

the nature of roots of quadratic equation is determined by
1^2+4*5 > 0 ==> hence there will be 2 roots and real

Answer 4
