GCF Review / Using the Distributive Property Wednesday August 15th
Determine the GCF for each of the following: 1. 2. 3. 4. 5.
Now let’s factor Example 4 • Factor 7x+14 using the GCF
Distributive Property • The Distributive Property- used to multiply a single term and two or more terms inside a set of parentheses. • This is also how we CHECK the GCF Factoring problems • Example: 3(x + 6) = 3(x) +3(6)
Practice 1. What is wrong here? 4(y + 3) = 4y + 3 2. (y + 7)y 3. 0.5n(n – 9) 4. (2 – n)(2/3)
More Practice (Try these w/ a partner) 5. -2(x + 7) 6. (5 – y)(-3y) 7. – (2x – 11) 8. ( )(2n + 6)
This combines Monday’s lesson with distributing… • Simplify the expression: 4(n+9) – 3(2 +n) Remember, PEMDAS
Practice (w/ a partner) Simplify the expression: 9. (4a – 1)2 + a 10. -6(v + 1) + v 11. 7(w – 5) + 3w 12. (s – 3)(-2) +17s
Translate the verbal phrase into an expression, then simplify 1. Twice the sum of 6 and x, increased by 5 less than x. 2. Three times the difference of x and 2, decreased by the sum of x and 10.
