I am really struggling to understand this topic. Can someone please explain augmented matrices and their systems of equations? I have read my textbook many times and can't understand it. I need this explained in an easy to understand way. Like math for dummies. Here's an example of a question that I don't know how to do. Can you please give a step by step explanation? I will give 25 points.

That's my answer

Step-by-step explanation:

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

i do not know the answer
