Task 4—Solving Rational Equations

Using the equation below as a model, fill in numbers in the place of a and b to create a rational equation that has an extraneous solution.

x plus a over ax = b over x

Part 1. Show all work to solve for x in the equation and check the solution.

Part 2. Explain how to identify the extraneous solution and what it means.

Answer 1

is that the only 2 parts you have

Answer 2

yea

Answer 3

We have to cross multiply to get:
x(x+1) = 2x
x^2 + x = 2x
x^2 -x = 0
x(x-1)=0
x=0 or x=1

The x=0 solution is extraneous because we are not allowed to divide by 0 (which is what happens in the original equation if x is 0). Do This Look Right Are Not

Answer 4

thank you :)
