Distributive Property

is a number, a variable or the product of a number and one or more variables.– In 3x2 + 4x +3---3x2, 4x and 3 are the terms.

Terms have: is a term that has no variable. is a symbol, usually a letter, that

represents one or more numbers. is the power to which the variable is

raised. is the number in front of the variable.

Terms Identify the coefficient, exponent, variable,

and/or constant for the following terms.• 7x3

• -8x2 – 4

• -3x2

• -9

• x5 + 5

Like Terms

For terms to be “like terms” everything must match except the coefficients.

Which of the following are like terms?

3x2 2x3

2x2 7x2

Like terms

Like terms can be added or subtracted. 3x + 5x

8y2s – 3y2s

Like Terms

Which terms are alike?5x, 8y, 9z, 10, 12x, 14z, 7, 12x2

Like Terms: 5x and 12xLike Terms: 10 and 7Like Terms: 9z and 14zTerm: 12x2

Term: 8y

Combine like terms:5x+ 8y + 9z – 10 – 12x – 14z + 7+12x2
