Solving with the Quadratic Formula

100

2p²+3p-2=0

p = 1/2 and -2

200

2m²-3m-5=0

m = 5/2 and -1

300

x²-6x+4

x = 5.23 and 0.76

400

2a²+a-21

a = 3 and -3.5

500

3x²-11x+10

x = 5/3 and 2

Solving with Factoring

100

x²-36

(x+6)(x-6)

x= -6 and 6

200

4x²-64

(2x-8)(2x+8)

300

6x²+6x-18

6(x²+1-3)

400

x²-5x-36

(x-9)(x+4)

500

3x²-2x-5

(3x-5)(x+1)

Parabola Key Features

100

Slideshow

Write as an ordered pair

{0,1}

200

Slideshow

line of symmetry

x=-1

300

Slideshow

x intercepts

(-3,1)

400

Slideshow

y-intercept

y=-3

500

These are all the 4 key features of parabolas / quadratic functions

roots / x intercepts / solutions / zeros

y intercept

axis of symmetry / line of symmetry

vertex

Random

100

This is the quadratic formula

-b plus or minus SQ Rt -b^2 - 4ac all over 2a

^{lol write this on the board}

200

This is the order of operations

P E MD AS

This is what Miss Case drinks every morning. Extra points for guessing the flavors (2 of them)

REDBULL (cucumber and pear)

Factoring Quadratics, or trinomials, tell us this about the graph

the roots / the x intercepts

This is the date that all late work for Miss Case's (your favorite teacher) foundations class

December 16th... you're welcome ;)
