Task 4—Solving Rational Equations
1 answer:
Answer:
Step-by-step explanation:
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 + 4 / 4x = 8 / x
Part 1. Show all work to solve for x in the equation and check the solution.
X + 4 / 4x = 8 / x
x(x + 4) = (4x)8
x^2 + 4x = 32x
x^2 + 4x - 32x = 32x - 32x
x^2 - 28x = 0
x(x - 28) = 0
X = 0 or x = 28
Part 2. Explain how to identify the extraneous solution and what it means.
The solution x = 0 is extraneous because you are not allowed to divide by 0.
