Learning Objectives
By the end of this session, students should be able to:
Define "like terms".
Identify like terms.
Simplify like terms.
Expand and simplify algebraic expressions.
4
Like Terms
Have the same variable raised to exactly the same power.
Examples:
4x, -x, 38x
-y2, 4y2, -17y2
8xy3, 19y3x, 35xy3, -12y3x
mn2p, pmn2, -4n2mp
Note: the order of the variables does not matter
5
Multiple Select
Which of the following will be considered like for 3m2n?
2n2m
-6nm2
7m2n
5mn
6
Simplification
Add / subtract LIKE terms
Examples:
5m2 + 8n2 - 6m2 + n2 - m2
= 5m2 - 6m2 - m2 + 8n2 + n2
= -2m2 + 9n2
-11a2b3 + 6b3a - 7ab3 + b3a2 - 9a3b
= -11a2b3 + b3a2 + 6b3a - 7ab3 - 9a3b
= -10a2b3 - ab3 - 9a3b
