Chapter 10, Problem 17CCSR
Solution

To identify : The extraneous roots of the given equation.

The extraneous solution is x=1 .

Given information :

The equation is: xx−1−2x=1x−1

Explanation :

Given equation is xx−1−2x=1x−1 .

First find the domain of the variable in the given rational equation. As you know division by zero is undefined, so exclude those which makes denominator zero.

  x≠0x−1=0x≠1

Thus, the domain is {x|x≠0,x≠1|} .

The Least Common Denominator of x and (x−1) is

  LCD=x(x−1)

Now multiply both the sides of the given equation by LCD .

  x(x−1)[xx−1−2x]=x(x−1)[1x−1]x(x−1)x2−2(x−1)x(x−1)=xx2−2(x−1)=xx2−2x+2=x

Subtract x from both the sides.

  x2−2x+2−x=x−xx2−3x+2=0x2−2x−x+2=0x(x−2)−1(x−2)=0(x−2)(x−1)=0x=1 or 2

Since, the value x=1 is outside the domain, this is excluded from the solution set.

Therefore, the extraneous solution is x=1 .
