Quadratic Equations
Zero Product Property
If , then
a = 0 or b = 0.

4. Use the Zero Product Property to solve for x.

5. Use the Zero Product Property to solve for x.

6. Solving Quadratics by Factoring
Step 1: Write the equation in STANDARD FORM!
y = ax2 + bx + c
Step 2: SET y = 0 !!!!
REMEMBER you are SOLVING (which means you want the x-intercepts)!
Step 3: Find the GCF.
Step 4: Factor the quadratic by special pattern or by factor cross.
Step 5: Use the ZERO PRODUCT PROPERTY.
