What does it mean when it asks for f(0). 

You plug in zero for x.

100

What is a perfect square? 

Anything that can be squared.  __ ^2 

100

Use zero product property. 

(x-5)(2x+4) = 0 

x= 5 and x= -2

100

Evaluate that (200+5)(200-5) is equivalent x2+72

No  x2- 72

100

Write in Standard form: 

(3x+7)(x+3)

3x2+16x + 21

200

Find f(0) if f(x) = (2x-6)(5x+24)

f(0) = (2(0)-6)(5(0)+24)

   = -6*24 = -144

200

Solve x^2 = 81

x= 9, -9

200

Use Zero product Property. 

(x+7)(x-5)=0

x = -7 and 5

200

Factor: 9x2 - 100 

(3x+10)(3x-10)

200

Write in Factored form: 

x2+8x + 15

(x+3)(x+5)

300

What property do you use to solve this? 

f(x)=0 if f(x)=(2x-6)(5x+24)

Zero product property!

300

Solve:  n2 + 7 = 107

n= +-10

300

What is the quadratic formula. 

x= -b+- sqrt(b^2-4ac) /2a

300

Factor and solve: 

x2+7x + 12 = 0 

(x+3)(x+4) = 0

x= -3 and -4

300

Write in factored form: 

x2 + 8x +3 

Cannot be done

400

Solve : f(x)=0 if f(x)=(2x-6)(5x+24)

x= 3, and x= -24/5

400

How many solutions does it have.

(x-1)2=16

Two solutions: 

x = 5, and x= -3

400

Solve using +- notation. 

2x2 = 32 

x = +- 4

400

Solve using +- notation. 


(x+4)2 = 25

x = -9 and x = 1

400

Complete the square. 

x2 -10x = -25 

x = 5

500

Find: f(x) = 0 

(x-30)(x+25)=0

x= 30, x= -25

500

How many solutions does it have and solve. 

(x-2)2= 0

One solution 

x= 2

500

Solve using the quadratic formula. 


x2+6x +15=0

cannot be done..... why???!!!!

500

Solve by quadratic formula. 

x2+5x+3 = 0


x= -5 +- sqrt(13) / 2

500

Complete the square. 

x2+ 18x+77 = 0 

x=-5 and x=-13
