Solving Quadratic Equations Discussion

MAT222: Intermediate Algebra

Solving Quadratic Equations

In this discussion, you will solve quadratic equations by two main methods: factoring and using the

quadratic formula. Please complete the following problems according to your assigned number.

Use FACTORING to solve:

Use the QUADRATIC FORMULA to solve:

x

–

x

–

6 = 0

·

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 Math Symbols handout for guidance

with formatting.

·

Present your final solutions as decimal approximati

ons carried out to the third decimal place.

Due to the nature of these solutions, no check is required.

·

Incorporate the following four math vocabulary words into your discussion. Use

bold

font to

emphasize the words in your writing. Do not write definition

s for the words; use them

appropriately in sentences describing your math work

.
