2. Factoring Polynomials By Miss Kaylaa

3. What is Factoring Polynomials¿ Cleary Defined Example – *Factoring is to express a polynomial as the product of monomials and polynomials*

4. Example: 2x 2 + 4x a(b + c) = ab + ac. Notice that each term has a factor of 2x, so we can rewrite it as: 2x 2 + 4x = 2x(x + 2)

5. Using it to find where parabolas hit the x-axis To solve equations Used in geometry to find the dimensions of a rectangle

7. The area of a rectangle is (a² - 3a – 18) square inches. This area is increased by adding 5 inches to both the length and the width. If the dimensions of the original rectangle are represented by binomials with integral coefficients, How does Farmer Kaylaa find the area of the new rectangle? Original Rectangle Area = (a² - 3a – 18)in²

8. a² - 3a – 18 = a² - [(-6) + 3]a - 18 = a² - 6a + 3a – 18 = (a² - 6a) + (3a –18) = a(a – 6) + 3 (a – 6) = (a + 3) (a – 6)
