2. 1.2 Distributive Property & Combining Like Terms
How can “Combining Like Terms” and the
“Distributive Property” be used to simplify expressions?

3. 7 x Like terms: Rules: Same Variable AND same exponent
Coefficients can be different (# attached to variable)
3. Constants are like terms (ie. like 5 and 3 )
Like Terms
Unlike Terms
3x and 2x
5x2 and 2x
The exponents
are different.
3.2 and n
Only one term
contains a
variable
6a and 6b
The variables
are different
w and w 7
5 and 1.8 7 x
Coefficient
Variable

4. Identify like terms in the list.
3t 5w2 7t 9v w2 8v
Look for like variables with like powers.
3t 5w2 7t 9v w2 8v
Like terms: (3t and 7t) (5w2 and 4w2) (9v and 8v)

5. Simplify.
A. 6t – 4t
6t – 4t
6t and 4t are like terms. 2t
Subtract the coefficients.
B. 45x – 37 – x + 4

6. Write an expression using the side lengths.
Geometry Application
Write an expression for the perimeter of the triangle. Then simplify the expression. x
2x + 3
3x + 2
Write an expression using
the side lengths.
Identify and group like terms.
Add the coefficients.

7. Your Turn: -5a + 4 - 2a -x + 2 + 8x - 5 6x + 8y 2x + 3 x + 1
3. Write an expression for the perimeter of the given figure
2x + 3
x + 1

8. You can use the Distributive Property to multiply numbers mentally by breaking apart one of the numbers and writing it as a sum or difference.

9. Simplify the expressions:
–2(3 – d)

10. Simplify the expression:
3d – (9 – 2d)

11. Simplify the expression:
3d – (9 – 2d)
