y = 2x^2 + 3x - 1 What values make y = 0?

OpenStudy (inkyvoyd):

(there are 2)

OpenStudy (anonymous):

Oh? OK, I'll keep that in mind, thanks.

OpenStudy (anonymous):

Did you type in the equation correctly?

OpenStudy (anonymous):

Yes, I did.

OpenStudy (anonymous):

When I graph it, x has fractional values.

OpenStudy (anonymous):

Then I guess the answers are fractions.

OpenStudy (anonymous):

I guess that makes sense, this equation does not seem factorable...

OpenStudy (anonymous):

Use the quadratic formula. \[(-3\pm \sqrt 17)/4\]

OpenStudy (anonymous):

OK, so is that the value you got for x? Also, inkyvoyd said there were 2 answers... Hmm...

OpenStudy (anonymous):

Yes -- there is a plus and a minus answer to the answer above.

OpenStudy (anonymous):

Oh yeah, almost forgot about that. XD Thanks for your help.
