STUDY! STUDY! STUDY! STUDY! STUDY! Review for test over polynomials: Add, subtract, multiply, divide, and name polynomials. STUDY! STUDY! STUDY! STUDY! STUDY!

4x Draw it out!  – 5 Explain HOW to find the missing side: “Add the 2 given sides and… subtract that from the perimeter.” --- add the 2 sides: 2x + 7 + 3x – 4 5x + 3 --- subtract that from the perimeter: ( 9x – 2 ) – ( 5x + 3 ) Distribute the minus sign. 9x – 2 – 5x – 3 CLT 4x 2x + 7 3x – 4 ??? Perimeter is 9x – 2 – 5

Remove the parenthesis… NOTHING CHANGES! 5a + 8b + 4c + 2a + b – c CLT 7a + 9b + 3c

REMEMBER: The power stays the same! Combine Like Terms 9d2 REMEMBER: The power stays the same! + 13d + 16

Distribute the minus sign. 7n2 + 3n – 2 – 3n2 + 8n + 13 CLT 4n 2 + 11n + 11

n2 + 14n + 49 Area = length • width Both are the same! Write the parenthesis twice: ( n + 7 ) ( n + 7 ) First Outer Inner Last n2 CLT + 14n n2 + 14n + 49 + 7n + 7n + 49

20k3 – 6 2k3 Quadrilateral means… 7k3 + 4 four sided shape. DRAW IT OUT!  Perimeter means… Add all sides. CLT 2k3 + 7k3 + 9k3 + 2k3 = 20k3 + 4 – 10 = – 6 Put them together… 20k3 – 6

SIX multiplications in all… a • 3a2 = 3a3 a • ( – a) = – a2 a • ( + 7) = + 7a – 4 • 3a2 = –12a2 – 4 • ( – a ) = + 4a – 4 • ( 7 ) = – 28 Combine like terms… 3a3 – 13a2 + 11a – 28

The formula is the same as a rectangle: Parallelogram is… 4-sided shape with… opposite sides parallel. The formula is the same as a rectangle: Area = base • height – 8p2 + 5p – 4 height ( ) 3p4 – 24p 6 + 15p 5 – 12p 4

4x + 3 A = l•w w = ― A l 24x2 + 18x 6x 24x2 + 18x 6x 6x 6x ??? Area is 24x2 + 18x Draw it out!  A = l•w w = ― A l 24x2 + 18x 6x 4x + 3 24x2 + 18x 6x 6x

6w2 – 11w – 10 Product means… MULTIPLY! First Outer Inner Last 6w2 CLT

Descending order means… from highest to lowest power of x. highest power of x 5x 3y next power of x + 9x 2y 3 next power of x – 7xy 4 last term NO x + 3y 2

Remember: When you divide… subtract the exponents! 18x9 + 36x5 – 12x4 6x4 6x4 6x4 Remember: When you divide… subtract the exponents! 3x5 + 6x – 2 On the last term, the x 4’s divide out… NO x in the last term.

Remember: When you divide… subtract the exponents! 36x6 – 45x5 + 99x2 – 63x 9x 9x 9x 9x Remember: When you divide… subtract the exponents! 4x 5 – 5x 4 + 11x – 7 On the last term, the x ‘s divide out… NO x in the last term.

3x 3 3x 2y – 5xy – y + 7 3x 2 – 5x + 7 3x 3y2 – 5xy – 7 3x 2 – 5x 3x 2y2 – 5x2y
