GCF Review / Using the Distributive Property Wednesday August 15 th

Determine the GCF for each of the following:

Now let’s factor  Factor 7x+14 using the GCF Example 4

 Factor 9x - 33 using the GCF

 Factor x 2 + 8x using the GCF

Factor using 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 (y + 7)y n(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)

Practice (w/ a partner) Simplify the expression: 9. (4a – 1)2 + a10. -6(v + 1) + v 11. 7(w – 5) + 3w12. (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.
