Well you're close.. you added 8 instead of subtracting. And it's \(-5 \pm\)
Because remember, when you get it in standard form it'll be \(0=x^2+5x+2\) And you plug those into the formula like so \(\Large \frac{-(5) \pm \sqrt{(5)^2-4(1)(2)}}{2(1)}\)
ok then im pretty sure its this \[-5 + or - \sqrt{17}/2\]
Yup, there you go!
wow thank you!
