Solving with the Quadratic Formula
Sec 9 - Solving for Exact Solutions with the Quadratic
FormulaHomework: Pg 269 #1-9, 43*EXACT answers unless there is a
word problem where a decimal would make more sense.
General Form of a Quadratic Equation
Quadratic Formula
Ex 1: Field HockeyA field hockey player makes a scoop that
releases the ball with an upward velocity of 34 ft/sec. The
function h = -16t + 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?Ex
2: Solve and Give Exact Solutions2x - 1 = 5x
15x + 2x + 1 = 0Steps:Put in General Form (must equal
0)Substitute a, b and c into the Quadratic Formula and
simplify.Break down the RadicalSplit into 2 Fractions (if
needed)Reduce the fractions (if needed)Ex 3: Solutions with Complex
Numbers
Ex 4: SADMEP or QF
How did you know when to use SADMEP and when to use the
Quadratic Formula?HOMEWORKPg 269 #1-9, 43*EXACT answers unless
there is a word problem where a decimal would make more sense.
