7/3

FOIL

100

(x + 1) (x + 2)

x2 + 3x + 2

200

(x - 4) (x + 3)

x2 - x - 12

300

(2x + 1) (3x + 4)

6x2 + 11x + 4

400

(4x - 3) (2x + 3)

8x2 + 6x - 9

500

(3x - 5) (3x - 4)

Solve for X

100

Solve for x: x + 2 = 10

x = 8

200

Solve for x: 3x - 2 = 10

x = 4

300

Solve for x: 2x + 3 = x - 6

x = -9

400

Solve for x: 3x + 6 = x + 10

x = 2

500

Solve for x: x2 - 5 = 20

x = 5

Arithmetic/Geometric Sequences

Geometric

200

Is this sequence Arithmetic, Geometric, or Neither? 1, 5, 6, 9, 10

Neither

300

Is this sequence Arithmetic, Geometric, or Neither? 3, 5, 7, 9, 11

Arithmetic

400

What is the common difference? 4, 8, 12, 16, 20

4

500

What is the common ratio? 4, 8, 16, 32, 64

2

Explicit/Recursive Formula

100

What is the first term of this Explicit Sequence? tn = 2n + 3

5

200

What are the first four terms of this Explicit Sequence? tn = 4n + 1

5, 9, 13, 17

300

What is the difference between the Explicit Formula and the Recursive formula?

Explicit: substitute in the number of each term (1 for 1, 2 for 2, etc) Recursive: substitute in the term before

400

What is the second term of this Recursive Sequence? t1 = 2 tn = tn-1 + 2

4

500

What are the first four terms of this Recursive Sequence? t1 = 0 tn = tn-1 - 4

0, -4, -8, -12
