■ CONCEPT SUMMARY & GUIDED NOTES: 6.14 · Part II
1The Distributive Property
2Strategy Model — step by step
  1. Expand: Multiply the outside factor by each term inside parentheses
  2. Factor: Find the GCF of terms and pull it outside: ab + ac = a(b + c)
  3. Visual: Represent as the area of partitioned rectangles
3Mathematical Word Bank
  • The Distributive Property (La propiedad distributiva) — Multiply a factor by every term inside parentheses.
  • Distributive Property (Propiedad distributiva) — Multiplying a number by everything inside the parentheses: a(b + c) = ab + ac.
  • Factor (Factor) — A factor of a whole number divides it evenly, with no remainder. For example, 3 is a factor of 12 because 12 ÷ 3 = 4.
  • Expand (Desarrollar) — To multiply out the parentheses in an expression.
  • Equivalent (Equivalente) — Expressions that always have the same value.
  • Coefficient (Coeficiente) — The number in front of a letter, like the 3 in 3x.
4Watch out
  • The most common mistake in The Distributive Property is multiplying the outside factor by only the FIRST term inside the parentheses and forgetting the second — for example, writing 3(x + 4) = 3x + 4 instead of 3x + 12. Before you submit, check: did the outside number reach BOTH terms inside the parentheses?
  1. 1 MULTIPLE CHOICE

    When using the distributive property with a(b + c), you must multiply 'a' by:

    1. ABoth b and c
    2. BOnly b
    3. COnly c
    4. Db + c first, then multiply
