2. Sample
Simplify:
2(3x)
(- 3y)(- 5)
(2x)(3y)(4w)

3. Process
Numbers
Variables

4. Try again
(-5)(3x)
(3x)x
(- 8x)(- 5)

5. Simplify
3(4 + 5)
Do another way?

6. Distributive Property
If a, b, c are any integer, then
a • (b – c) = a • b – a • c or
a • (b + c) = a • b + a • c

7. News carrier
Newspaper to two houses

8. Use the distributive property
Simplify:
5(3x – 2)
- 9 (2y + 7)

9. Simplify
c) - (a + b)
d) - (6x + 2 – 8y)

10. Summary Simplify monomials. Simplify using the distributive property.
Simplify the negate of a sum.
