Question

y=x^2-x-12

Answer 1

What about it?

Answer 2

An equation is not a question.

Answer 3

calculate discriminant :
\[D = b ^{2}-4ac\]
than
\[x = \frac{ -b \pm \sqrt{D}}{ 2a }\]

Answer 4

this counts for all second degree equations \[ax ^{2}+bx+c=0\]

Answer 5

You are missing the objective of math.

To state and solve problems.

Answer 6

You have not stated a question @mabreyc

Answer 7

I don't think the sole purpose of math is to state problems :). You're getting philosophical there hhe. The only reasonable question here was to calculate the zero points of the function. So I gave him the tool to do that :)

Answer 8

But you're right. His question is incomplete.

Answer 9

Yes, that is a reasonable assumed question, but math is supposed to teach learning skills and one of those skills is:
How to ask questions.
There is nothing philosophical about that :-)

Answer 10

Yes, you're absolutely right :-)
