Read the Math Notes box for this lesson. For each of the following expressions, first indicate how many terms it has, and then combine like terms to simplify each algebraic expression, if possible. If it is not possible to simplify the expression, explain why not. Homework Help ✎
3y + 2y + y2 + 5 + y
3y2 + 2xy + 1 + 3x + y + 2x2
3xy + 5x + 2 + 3y + x + 4
4m + 2mn + m2 + m + 3m2
Combine like terms.
3y + 2y + y + y² + 5
6y + y² + 5
Arrange from the highest to the lowest power.
y² + 6y + 5
Is there any way to combine terms?
Remember, you can only add terms if they have the exact same variable.
