7c^4-4c^3+28c^2-16c factor it by grouping

Question

i do not for the life of me understand this factoring by grouping on trinomials or any of the polynomials, bi nomials. i hate algebra!!!

Answer 1

Nate, read, reread, and reread again what Kenneth said. I used to be a math teacher and I heard " I hate math" more than you can imagine. You say you hate algebra because you are having difficulty with it. As soon as you get the hang of it you will have a different attitude. Enough lecturing. Here's a hint for the problem:

Look at the 7, the 4, the 28, and the 16.

Group the terms with the 7 and 28 and group the terms with the 4 and 16 because in each case one number is a factor (or multiple) of the other.

(7c^4+28c^2)+(-4c^3-16c)

now factor each set of parentheses by taking out the GCF of each set of parentheses and finish up from there

Answer 2

Hating Algebra is not a smart strategy for you. You have a considerable number of mathematics courses ahead of you, and Algebra will be at the heart of most of them.

 

By concentrating on dislike, and seeking to blame something outside you, you are beginning a pattern of failure, and that will bring much unhappiness and stress to you.

 

I suggest that you completely reform your attitude and your approach to school. If you do not try to learn, and that involves careful listening and thinking, it's most unlikely that you can succeed.

 

I recommend that you do ALL of the following.

1.  Read your textbook or other instructional material. Read it more than once, or twice--read until you 'get it' or until at least you know what questions to ask when you seek help.

2. Listen in class; think, then ask questions in the desire to understand

3. Get help from tutoring opportunities at school (perhaps after class).

4. (Optional) Get a paid tutor, from whom you will try to learn. Do NOT use a tutor just to do your homework.

5. Google "Factoring trinomials" to get lots of resources for learning, including Khan Academy.
