Question

In the equation y= (1/X-1 )+( 1/X+1), taking x = -3 and x -1/3 , compute y.

Answer 1

Answer:

y=-2/3 and -6

Step-by-step explanation:

y= (1/X-1 )+( 1/X+1)

Taking x=-3

y= (1/(-3)-1 )+( 1/(-3)+1)

y= (-1/3-1 )+(-1/3+1)

y= (-4/3 )+( 2/3)

y=-2/3

y= (1/X-1 )+( 1/X+1)

Taking x=-1/3

y= (1/-1/3-1 )+( 1/-1/3+1)

y= (-3-1 )+(-3+1)

y= (-4)+(-2)

y= -6
