Factoring Using Special Patterns General Algebra II

2. Solving Equations with Special Patterns by Factoring:
Step 1: Set the equation equal to 0.
Step 2: Factor (mono out first if possible, difference of two squares, perfect trinomial squared).
Step 3: Set each factored term equal to 0.
Step 4: Solve for the solutions.

3. Solve the equation by factoring.

4. Solve the equation by factoring.

5. Solve the equation by factoring.

6. Solve the equation by factoring.

7. Solve the equation by factoring.

8. Finding the zeros of a function:
Step 1: Substitute 0 in for y or f(x)
Step 2: Factor
Step 3: Set each factor equal to zero and solve
Step 4: Write your solutions as coordinates
****This is different from solving an equation because there are now two variables (x, y).
****Your solutions should be in coordinate form ( , 0), ( , 0)
****”Zeros” are x – intercepts

9. Find the zeros of the function.

10. Find the zeros of the function.

11. Find the zeros of the function.
