1. Sec 9 - Solving for Exact Solutions with the Quadratic Formula
Homework: Pg 269 #1-9, 43
*EXACT answers unless there is a word problem where a decimal would make more sense.

2. General Form of a Quadratic Equation
Quadratic Formula

3. Ex 1: Field Hockey
A field hockey player makes a scoop that releases the ball with an upward velocity of 34 ft/sec. The function h = -16t² + 34t models the height of the ball after t seconds. When will the ball reach a height of 15 ft?
Think About It: Why would SADMEP not work in this situation?

4. Ex 2: Solve and Give Exact Solutions
2x² - 1 = 5x
15x² + 2x + 1 = 0
Steps:
Put in General Form (must equal 0)
Substitute a, b and c into the Quadratic Formula and simplify.
Break down the Radical
Split into 2 Fractions (if needed)
Reduce the fractions (if needed)

5. Ex 3: Solutions with Complex Numbers

6. Ex 4: SADMEP or QF
How did you know when to use SADMEP and when to use the Quadratic Formula?
