3x^2+2x-5=0

Answer 1

given the form

\[ax^2+bx+c=0\]

the quadratic formula is

\[x= \frac{ -b\pm \sqrt{b^2-4ac}}{2a}\]

i suggest you memorize this formula

Answer 2

I do have it memorized

Answer 3

then what is your issue?

Answer 4

But just because I have it memorized doesn't mean I got the question right. So im trying to see what I did wrong. That's my issue.

Answer 7

no, im trying to see if you made a mistake when calculating

Answer 8

Answer 9

\[\frac{ -2\pm \sqrt{(2^2)- 4(3)(-5)} }{ 6 }\]

is this how you set it up?

Answer 10

yeah
