MATH114N Week 1 Discussion Latest November

Let’s look more closely at the greatest common factor (GCF) of a problem. Apply your knowledge of GCFs (13.1) to simplify a problem presented by a classmate. You will need to factor the problem and post your simplified expression. Then, post another example for someone else to simplify. I will start the discussion with this expression.
Simplify: 56×7 + 21×4 + 63×3
I am looking forward to seeing your problem and simplified expressions. Don’t forget to check that your classmate answered correctly.
Each time you post, you should post a solution and a new problem for a classmate to solve. This keeps the discussion fresh and provides you with many solutions on the week’s topics. Use these as references if you are stuck on a topic. Please don’t everyone answer my original problem (this will get really boring!), but look at the bottom of the discussion for the latest one posted by a classmate and respond to it. Try this one or the original one to start you off and let’s work from there. Remember, no repeats!

MATH114N Week 2 Discussion Latest November

As you become more familiar with factoring, you will notice there are some factoring problems that follow specific patterns.These patterns are known as
a difference of squares;
a perfect square trinomial;
a difference of cubes; and
a sum of cubes.
Choose one of the four forms above. In your own words, explain the pattern that allows you to recognize the binomial or trinomial as having special factors.Then provide an example of a binomial or trinomial expression that may be factored using the special technique you explained.

MATH114N Week 3 Discussion Latest November

This week, we begin graphing systems of simultaneous equation. Before we begin looking at the many graphs you can find out on the Web, let’s review our knowledge of 2-D graphs. These graphs are known as 2-D because they have two axes. One you are familiar with is the xy-graph, which has an x axis and a y-axis.Please provide one fact about these graphs. If you do not remember them, use the book or the Internet to find terminology associated with these graphs. There are a lot of terms associated with these graphs, so please do not repeat a classmate’s term. You may also discuss different types of standard graphs that you might have seen and should recognize. Let’s see what you know about graphs.

MATH114N Week 4 Discussion Latest November

There are three ways of solving systems of linear equations: graphing, substitution, and elimination. Post a problem and show your step-by-step solution using one of the three methods. Now go and check out a classmate’s problem and solution. Is he or she correct? If not, are you able to point out the error so he or she can fix it? Let’s help each other find those common mistakes that we all make but are hard to track down in our solutions.

Don’t forget to do a check! Put your points into the original equation and check that they make both equations true. Why is this so important? If your point does not work in your original problem, your solution is not correct. Don’t forget to show your check process.

week 5

In your own words, define a square root. Then, let’s practice finding the square roots of numbers. You will need to find the square root of the problem and post another one for your classmates to solve.

Don’t forget to post a solution and then a new problem for a classmate to solve.

week 6

Apply your knowledge of square roots to solve equations involving them. Show your step-by-step solution. Then, post another example for someone else to solve. Remember, each problem should have two solutions.

I will start the discussion with this expression. Solve:
(5x – 4)2= 36

Don’t forget to check that your classmate answered correctly!

week 7

Functions seem like they have a language of their own. Let’s look at this new language and the terms it uses. You see terms such as: relation, function, functional notation, x-intercept, y-intercept, axis of symmetry, maximum (of a function), minimum (of a function), and vertex.

Pick one of these terms and explain the term to your classmates in your own words. Then review a classmate’s explanation of the term and comment on it. Do you have a better way to understand the term? Share your way with us.
