Question

2
4n - 3n - 1
3n
___________



the 2 floating means to the second power

which means its 4n to the second power

they want me to multiply

also thanx to all the people who answered! And to u rude ones out there this is the way it was written in the book so if u have a problem with it dont type anything at all cuz I dont want to hear ur opinion I just need help with this math problem. And yes it is written poorly thats why I dont understand it!

Answer 1

Do it this way: 3n x ( 4n² - 3n - 1) and multiply each term out, and you get 12n³ - 9n² - 3n. As how to show the actual work, I will leave you to that.

Answer 2

The keyboard notation to write "4n to the power of 2" would be 4n^2.

As for the rest, I think you'll have to clarify your question.

(added later: I did not want to be rude, your question did not originally say you wanted to multiply those two lines. I really really did not know, and your question really, really, was not clear. xxtraswe is right. your question originally was very poorly stated.Maybe it was written like that in your text book, but we do not know the context of your text book, like the heading that says: "multiply the following". Even if I now look at everything above the first "Additional details", I can to some extent understand the "rude" comment from xxtraswe. Your question did not make any sense at all. Please be mindful of that next time. If they want you to multiply, you need to say that up front.

All the answers that solved your problem were submitted after you clarified that)

Answer 3

(4n² - 3n - 1) * 3n

Just distribute 3n through the parentheses (multiply it by each part of 4n² - 3n -1) as shown below:
(4n² * 3n) + (-3n * 3n) + (-1 * 3n)

Now simplify:
= 12n³ - 9n² - 3n

Answer 4

12n^3 - 6n^2 - 3n
the ^3 means to the third power and ^2 means squared/to the second power. hope this helps
oh, and if you're not understanding this hun i suggest you go talk to your teacher at lunch tomorrow k?

Answer 5

u mean 4n² - 3n - 1 and what is the 3n at the bottom

(4n²-3n-1)(3n)

=12n³-9n²-3n

Answer 6

Trust me honey with the way this question is written, it seems like you need a little more than just MATH help to me!

Answer 7

let (4n^2-3n-1)x3n =0

we ca get (4n^2-3n-1)
=( 4n+1)(n-1)


so,
(3n)(4n+1)(n-1)=0

3n=0............4n+1=0 ...........n-1=0
n=0..............n=-1/4...............n=1

so, we get
n=0 or -1/4 or 1
