Combining Like-Terms
Introduction: What does it mean to combine like-terms? Like-terms are when the
variables and powers of two numbers are the same. You can combine these
numbers simply by adding or subtracting their coefficients, or the number in front
of the variable.
Task: You will be looking at different websites and watching videos to help you
understand the concept of combining like-terms. You will then use your newly
found knowledge to evaluate practice problems.
Process: First watch this video on combining like terms and follow along with the
examples. Once you have completed that, read this lesson. After you have done
both of those things, you may begin doing the practice problems on this
worksheet.
Evaluation: You will be evaluated on your participation and how well you do on
the worksheet. There is a total of 20 possible points.
Conclusion: Remember, you can’t combine grapes and apples. You can only
combine grapes with grapes and apples with apples. It’s the same for X and Y
variables when combining them. For more explanations, visit:
