What are polynomials?

• Expressions that consist of only variables

• Expressions that consist of only constants

• Expressions that consist of variables of the same power

• Expressions that consist of constants and variables of different powers

What are like terms in algebra?

• Terms that contain different variables raised to different powers

• Terms that contain the same variable raised to the same power

• Terms that contain the same variable raised to different powers

• Terms that contain different variables raised to the same power

What is the rule for adding like terms in polynomials?

• The like terms are always subtracted

• The like terms are never combined

• The like terms are always combined and added

• The unlike terms are always combined and added

What is the first step in adding algebraic expressions using the horizontal method?

• Place the polynomials in a vertical arrangement

What are unlike terms in algebra?

• Algebraic terms which do not have the same literal coefficients and cannot be raised to the same power

• Algebraic terms which do not have the same literal coefficients and can be raised to the same power

• Algebraic terms which have the same literal coefficients and cannot be raised to the same power
