1. 8.1.3 How can I factor this? Factoring with Special Cases
Goal: Factor special case quadratics.
Standard: A‑SSE.3a. Factor a quadratic expression to reveal the zeros of the function it defines.

2. Factor the quadratic.
1. x2 + 6x + 9

3. Factor the quadratic.
2. 2x2 + 5x + 3

4. Factor the quadratic.
3. x2 + 5x - 7

5. Factor the quadratic.
4. 3m2 + m - 14

6. Special Cases Most quadratics are written in the form ax2 + bx + c.
But what if a term is missing?
Or what if the terms are in a different order?
Consider these questions while you factor the following
expressions.

7. Special Case: Middle Term Missing
a. 9x2 - 4

8. Special Case: Constant Missing
b. 12x2 – 16x

9. Special Case: Out of Order
c k2 – 10k

10. Special Case: Out of Order & Missing Squared Term
d – 100m

11. Final Question
Factor the quadratic. Be ready to share your answer with the class.
4x2 – 10x - 6
