slide5
Add and Subtract Polynomials - 100

(2x2 + 5x) + (7x2 + 3x + 11)

Board

Answer

slide6
Add and Subtract Polynomials - 100

(2x2 + 5x) + (7x2 + 3x + 11)

Since you are adding the two polynomials the parentheses mean nothing

2x2 + 5x + 7x2 + 3x + 11

Combine like terms

9x2

+ 8x

+ 11

Board

slide7
Add and Subtract Polynomials - 200

(x2 + 8x – 11) + (x3 + 3x2 + 11)

Board

Answer

slide8
Add and Subtract Polynomials - 200

(x2 + 8x – 11) + (x3 + 3x2 + 11)

Since you are adding the two polynomials the parentheses mean nothing

x2 + 8x – 11 + x3 + 3x2 + 11

Combine like terms

x3

+ 4x2

+ 8x

+ 0

x3 + 4x2 + 8x

Board

slide9
Add and Subtract Polynomials - 300

(2x2 – 5x3) – (7x3 – 2x2 + 11)

Board

Answer

slide10
Add and Subtract Polynomials - 300

These signs must change

(2x2 – 5x3) – (7x3 – 2x2 + 11)

Since you are subtracting the two polynomials the parentheses are very important

2x2 – 5x3 – 7x3 + 2x2 – 11

Combine like terms

-12x3

+ 4x2

– 11

Board

slide11
Add and Subtract Polynomials - 400

3(9x2 – 5x) – (x3 – 2x2 + x – 4)

Board

Answer

slide12
Add and Subtract Polynomials - 400

Distribute the 3

These signs must change

3(9x2 – 5x) – (x3 – 2x2 + x – 4)

Since you are subtracting the two polynomials and multiplying the first by 3, the parentheses are very important

27x2 – 15x – x3 + 2x2 – x + 4

Combine like terms

-x3

+ 29x2

– 16x

+ 4

Board

slide13
Add and Subtract Polynomials - 500

(x + 3) + (7x2 – 5x) – (3x3 – x2 – 4x – 6)

Board

Answer

slide14
Add and Subtract Polynomials - 500

These signs must change

(x + 3) + (7x2 – 5x) – (3x3 – x2 – 4x – 6)

x + 3 + 7x2 – 5x

– 3x3 + x2 + 4x + 6

Since you are adding the first two polynomials the parentheses mean nothing.

Combine like terms

-3x3

+ 8x2

+ 0x

+ 9

-3x3 + 8x2 + 9

However, you are subtracting the third so the parentheses are very important

Scientific Notation - 100

Rewrite in scientific notation

23,000,000

Board

Answer

slide26
Scientific Notation - 100

Rewrite in scientific notation

23,000,000

The decimal is at the end of a whole number

23 000 000

= 2.3 x 107

In scientific notation the decimal goes after the first digit.

You need to know how many place values you have to move the decimal

slide27
Scientific Notation - 200

Rewrite in scientific notation

0.000345

Board

Answer

slide28
Scientific Notation - 200

Rewrite in scientific notation

0.000345

You can see where the decimal is

0.000345

= 3.45 x 10-4

In scientific notation the decimal goes after the first digit.

You need to know how many place values you have to move the decimal

Perimeter is 40x2

Answer

final jeopardy question47
Final Jeopardy Question

Find the area of the rectangle

5x2 + 5x2 = 10x2

15x2

5x2

5x2

So the other 2 sides add up to 30x2

15x2

Area = length times width

Perimeter is 40x2

Area = 15x2 5x2

If the perimeter is 40x2,

what is the length?

Area = 75x4
