@Makayla43 Time for you to try. What is the coefficient of x^2?

- anonymous

b^2 - 4ac|dw:1340769023413:dw|

- Callisto

Too many hints already...

- farmdawgnation

I'm inclined to agree.

- anonymous

Omg. Forget this. I don't understand it and none of ya'll are helping. Bye.

- anonymous

It's due tomorrow so I'm screwed.

- Callisto

You should tell us what you don't understand so that we can help.

- anonymous

Everything.

Can you evaluate what timo gave you?

- anonymous

B^2-4ab. No.

- Callisto

Okay, let's start from the beginning.
You may take coefficient of a term as the number before the term.
For example coefficient of x in the term 8x is 8.
Now, in your question, the term is 2x^2. Can you identify the coefficient of x^2?

- anonymous

No...

- Callisto

By the way, it's b^2 - 4ac, not b^2 - 4ab

- Callisto

Do you understand the example?

- anonymous

I typed it wrong.

- anonymous

No I do not.

- Callisto

Which part you don't understand?

- freckles

The coefficient is the constant multiple

- freckles

constants are numbers that don't change

- anonymous

Everything.

- Callisto

Including?

- freckles

8x
8 is a constant
x is a variable
and actually 8 here is a constant multiple
and is therefore the coefficient of x

- freckles

8 here is called a constant multiple because it is being multiply by that variable

- freckles

So in 2x^2
What is the coefficient of x^2?

- Callisto

@Makayla43 are you still here?

- anonymous

No.

- anonymous

:P lol

- Callisto

I wonder how you can respond when you're not here....
Back to the question, after @freckles 's detailed and clear explanation, which part you still don't understand?

- anonymous

the i don't wanna study lol
