3. Solving Quadratic equations by taking the square root
x2 + 4 = 16
Test Review
When is this method used?

4. What quadratic equation has roots of 2 and 5?
Solving Quadratic equations by factoring
Write the equation represented by this graph
What are the solutions to the
quadratic equation x2 - 2x = 15?

5. Find the AOS, vertex coordinates, and the minimum or
maximum value
The Parabola
What are the coordinates of the point translated
from the y-intercept?
y = 2x2 – 4x – 5
The quadratic parent function, y = x2, has been made 50% wider,
shifted three places to the left, and moved 4 units up.
What is the new equation?

6. Other Examples:
Solve for x: x = 36
4 x
(x - 4)2 = 24 (x - 4) = ± 24
Factor out any perfect squares
And place them here.
2 6x - 4 =
x = 4 2 6

7. Other Examples:
What type of equation is this?
Complete the square and find the solutions
Then what method is used to solve this equation?
Solve
Find the solutions of x2 + 6x - 1= 0
Can you solve by factoring? By taking the square root?
Completing the square
x2 + 6x = 1 x2 + 6x + =1+9 9 (x + 3)2 = 10
x + 3 = 10 x = -3 10

8. Class work 4.3
 Do odd or even based on the last digit of your
code
4.3 is due before end of class tomorrow
