Participate in Discussion

Exponents and Expressions The purpose of this assessment is to help you determine whether you have a clear understanding of radicals and rational exponents, polynomials, and rational expressions, and provide you feedback to clarify any misunderstandings. The discussions for this class center on reviewing sample problems that were solved incorrectly. From the list of incorrectly solved problems, pick a problem that has not been discussed yet, and perform the following tasks:

1. Identify the error made in the solved problem.

2. Correctly solve/simplify the problem showing all the steps. Be sure to include any formulas or properties that support the correctly solved problem.

3. Write a few sentences explaining how to avoid making this mistake in future practice.

4. Reply to other students agreeing or disagreeing with your responses, and add any additional advice to avoid making these types of mistakes in future practice

Problem # 24

2𝑥2−23𝑥+11
