Apparently one of the numbers in my answer is wrong, don't know which one it is though

OpenStudy (dayakar):

a=5,b=-4,c=3\[x= \frac{ -b \pm \sqrt{b ^{2}-4ac} }{ 2a }\] \[x= \frac{ -(-4)\pm \sqrt{(-4)^{2}- 4 \times 5 \times 3} }{ 2 \times 5 }\]

OpenStudy (dayakar):

\[x= \frac{ 4 \pm \sqrt{16 -60} }{ 10 }\] \[x= \frac{ 4 \pm 2\sqrt{-11} }{ 10 }\] \[x= \frac{ 2 \pm \sqrt{11}i }{ 5 }\]
