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

lol ik haha

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

  • amistre64
the discriminate gives us a +number, so there are 2 solutions

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

minus the all

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
