<u>Quadratic Equation</u>
A quadratic equation also called a second-degree equation is a special polynomial whose highest degree is two.
The general form of the quadratic equation is
Where a is known as the leading coefficient. Another form to write the quadratic equation is
Where x1 and x2 are the roots or zeroes of the equation.
We have the roots of the given equation are -2 and 2, and the leading coefficient is 3.
Plugging in the given values we have
Operating

A cosmetics company conducted a survey to anticipate potential sales of various new products from its upcoming catalog. The survey was conducted by randomly selecting women from two different age groups with 400 women in each group. The women selected the product that they would most likely purchase when it became available. The results obtained are given in the table shown below.
Products Ages 21 - 30 Ages 31 - 40
Product 1 163 152
Product 2 84 89
Product 3 104 109
Product 4 49 50
Which of the following statements about the data above is true?
A.
The estimates for both age groups show an equal number of women would have voted for Product 3.
If you are trying to simplify 36(pi)/4, then 9(pi) would be what you want because it is the simplest form of that fraction. It also depends on the answer choices. Sometimes they want simplest form and other times they’ll have you leave the fraction as is. Typically simplifying completely is your best bet though.
Hope this helps!
