Question

lgbasallote · Answer

what is the degree of the equation?

anonymous · Answer

Find the number of solutions of –3x^2 – 2x – 3 = 0.

lgbasallote · Answer

so what do you think is the degree?

anonymous · Answer

second

lgbasallote · Answer

second degree...so the degree is 2 right?

anonymous · Answer

yes

lgbasallote · Answer

the number of solutions is then just equal to the degree

well if you haven't learned about complex numbers yet, then there are no solutions (if you get complex numbers as your solutions)

No real solutions, only complex. http://www.wolframalpha.com/input/?i=-3x%5E2+-+2x+-+3+%3D+0

lgbasallote · Answer

well the question was just "number of solutions".....

jim_thompson5910 · Answer

true, but in most classes I've seen, complex numbers aren't learned until later

So if the discriminant is negative, then you simply say "no real solutions" and you leave it at that.

i still think it's just asking "number of solutions" regardless if it's real or not...but let's ask anyway @alittlehaphazard what's your lesson
