PREALGEBRA: Mark Up!

Markup and Selling Prices






The amount that the cost of an item will increase is called a MARKUP.  This increase is based on a percentage of the cost.

The SELLING PRICE is the sum of the original cost and the markup.

HOW DO I:  selling price = wholesale + markup

Consider a proportion

ALGEBRA: Three Methods of Factoring Quadratics

"Box" Method Without Factoring First

"Box" Method With Factoring First

"Differences of Squares"
Example:  x² – 4 = (x – 2)(x + 2)

"Removing Common Factors" or "GCF"  "GREATEST COMMON FACTOR"

Example:  2x² + 4x

Notice that each term has a factor of 2x, so we can rewrite it as:

2x² + 4x = 2x(x + 2)

So you're sitting at home and you happen to visit our classroom blog.  Here are five problems that will help you prepare for the quiz tomorrow.  If you leave your answers in the comment section, I'll be back later today to give the answers.


Thanks for stopping!

1.  Factoring Quadratic Expressions

                    2x² + 5x + 3


                    7x² − 45x − 2

    Factoring - THIS ONE IS CHALLENGING  - Concept we learned yesterday!  Factor what you can then use the QUADRATIC FACTORING method!

                28nx⁴ + 16x³− 80x²

2.  Factoring a Difference of Perfect Squares
                      x² - 49


                    10x²  - 64
