how do you know whats what?

anonymous · Answer

When using the quadratic formula $$ax^2+bx+c=0$$ is the form. So based on your eqaution $$x^2-7x-6$$ what is in the place of a, b and c.

anonymous · Answer

a=x^2 b=-7 c=6 ?

anonymous · Answer

close a is the coefficient on x^2 not the x^2 itself. (Do you know what a coefficient is?)

radar · Answer

(a) is not the variable itself, but the coefficient, which is the numerical value that is being used to multiply the variable, if none is there then a=1.

anonymous · Answer

Thanks Radar....but the question was for lashell123... :-)

radar · Answer

Yes, and I want lashell123 to determine  "a"

radar · Answer

It was obvious the post, lashell123 did not understand "1" as a coefficient when it was not shown.

anonymous · Answer

So do I ...but she seems to be away at the moment.

anonymous · Answer

And that is why I was walking her through it. Please don't take offense.

radar · Answer

She has closed the question, but I thought she might still be viewing it, or still interested in solving it.

radar · Answer

No offense taken, and you were indeed helping her  learn.
