Warm Up Homework 6.1 Check

Warm-Up # 2 (2.25.2014) Simplify #1 and 2 1. 2. 3. Find, Describe, and Fix the error! Line 1: (4x2 – x + 3) – (3x2 – 8x – 9) Line 2: 4x2 – x + 3 – 3x2 – 8x – 9 Line 3: 4x2 – 3x2 – x – 8x + 3 – 9 Line 4: x2 – 9x – 6

Essential Question (2.26.2014) How does the distributive property apply to multiplying polynomials?

Take 5 minutes in Pairs: On the worksheet from yesterday. Complete the perimeter problems? What is perimeter? The distance around the outside of the figure!! How do I find Perimeter? Add up the lengths of all the sides!!

Multiplying Monomials Multiply Coefficients & Add Exponents of same base (4x2)(5x) 2. (-2xy)(6x4y) 3. (-3w)(-4w) 4. (5yz3)(xyz)

Multiplying Monomials and Binomials When you are multiplying a Monomial with a Binomial or Trinomial you DISTRIBUTE to each term! 3x(-2x + 3)

Practice Problems: 1. x(5 + 3) 2. (y – 6)(-5) 3. 2x(2x + 5) 4. 5.
