LEQ: How do we use factoring to determine zeros of polynomial functions? 

Warm­Up:

f(x) = 2x ­ 4 g(x) = ­x2 + 3x + 2 h(x) = x2 + 7x

How many zeros could the following functions have based on their degree? (First solve the algebraic operation, then answer the question) 

1. f(x)

2. g(x)

3. h(x) + g(x) =

4. g(x) + h(x) =

5. g(x) ­ f(x)  =

6. h(x) ­ g(x) =
