Present your final solutions as decimal approximations carried out to the third decimal place.

In this discussion, you will solve quadratic equations by two main methods: factoring and using the quadratic formula. Read the following instructions in order and view the example to complete this discussion. Please complete the following problems according to your assigned number. (Instructors will assign each student their number.)

 

If your assigned number

is

Use FACTORING to

solve:

Use the QUADRATIC FORMULA to

solve:

37 3×2 – x – 24 = 0 24 on p. 680

 For the factoring problem, be sure you show all steps to the factoring and solving. Show a check of your solutions back into the original equation.

 For the quadratic formula problem, be sure that you use readable notation while you are working the computational steps. Refer to the Inserting….

Quadratics – Solving with Radicals

Objective: Solve equations with radicals and check for extraneous solu- tions.

Here we look at equations that have roots in the problem. As you might expect, to clear a root we can raise both sides to an exponent. So to clear a square root we can rise both sides to the second power. To clear a cubed root we can raise both sides to a third power. There is one catch to solving a problem with roots in it, sometimes we end up with solutions that do not actually work in the equation. This will….

Find a for the equation of the least-squares line.

It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. Suppose that the following data were obtained for a collection of archaeological sites in New Mexico:Find a for the equation of the least-squares line.
