Sorry, I was not paying attention in my deleted response (see how easy it is to go too quickly and get it wrong?!). @mew55 is correct...you do need the quadratic formula: \[x = \frac{b \pm \sqrt{b^{2}  4ac}}{2a} = \frac{3 \pm \sqrt{3^{2}  4(5)(8)}}{2(5)} = \frac{3 \pm \sqrt{9  160}}{10} = \frac{3 \pm \sqrt{151}}{10}\] 151 is a prime number, so you can't simplify any more than that without a calculator.

does the 'i' needs to be simplify since the inside of the square root is 151?

Forgot the negative in the final square root...should be: \[\frac{3 \pm \sqrt{151}}{10}\]

@mew55...you could: \[\frac{3 \pm \sqrt{151}(i)}{10}\]
