 Amsco Integrated Algebra I: Addition and Subtraction of Radicals
This is a free lesson from our course in Amsco's Integrated Algebra
This lesson explains how to add and subtract like and unlike radicals. Like radicals are radicals those have the same index and the identical radicand. To add and subtract them:
• add or subtract the coefficients of the radicals
• multiply the sum or difference obtained by the common radical. For example: 2√3+5√3= (2+5) √3 = 7√3.

(Continued from above) Unlike radicals are radicals that have different radicands or different indexes or both. To add and subtract them:
• simplify each radical if possible
• combine like terms by using distributive property
• write the indicated sum or difference of the unlike terms.
For example, √3a2+12√a2=√3*√a2+12*√a2=a (√3+12)
Note: The sum or difference of unlike radicals cannot always be expressed as a single term. The video above further explains with the help of several examples.


As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Trigonometry by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at
