need help solving quadratic equation..

OpenStudy (amistre64):

.... ..... .. .... . .. . .... .... .. . .... . (morse code)

OpenStudy (anonymous):

I need to consider this problem.. \[3x ^{2}+x-5=0\] And then use discriminant \[b ^{2}-4ac\] and then solve with the formula \[x=-b + or - \sqrt{b sqar-4ac} a\]

OpenStudy (anonymous):

haha morse code?....

OpenStudy (anonymous):

sorry that took so long, idk how to do the formula right on this thing.. does it kinda make sense though?

OpenStudy (anonymous):

ok so the squared part of that is all over 2a

OpenStudy (amistre64):

it makes sense :)

OpenStudy (anonymous):

lol ik haha

myininaya (myininaya):

do you mean \[x=(-b+\sqrt{b^2-4ac})/2 \] and \[x=(-b-\sqrt{b^2-4ac})/2 \]

OpenStudy (amistre64):

the discriminate gives us a +number, so there are 2 solutions

myininaya (myininaya):

why does it put the a so close to the x? its hard to read

myininaya (myininaya):

to c*

OpenStudy (amistre64):

-1/6 +- sqrt(61)/6

myininaya (myininaya):

yay i left out the time a in the denominator lol

OpenStudy (anonymous):

sorry my computer was being slow so everything you guys said just loaded.

OpenStudy (anonymous):

I left off with \[-1\sqrt{-59} all \over 6\]

OpenStudy (anonymous):

minus the all

OpenStudy (anonymous):

so i'm not sure if i do something with i at this point..or if that is even correct what I have.. if that was the answer someone gave up there I guess I'm not sure what that's supposed to look like typed out
