## anonymous 5 years ago need help solving quadratic equation..

1. amistre64

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

2. 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 $x=-b + or - \sqrt{b sqar-4ac} a$

3. anonymous

haha morse code?....

4. anonymous

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

5. anonymous

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

6. amistre64

it makes sense :)

7. anonymous

lol ik haha

8. myininaya

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

9. amistre64

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

10. myininaya

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

11. myininaya

to c*

12. amistre64

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

13. myininaya

yay i left out the time a in the denominator lol

14. anonymous

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

15. anonymous

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

16. anonymous

minus the all

17. 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
