Reil [10]
Factor
find wht 2 numbers add to 8 and multiply to 3
none do

use quadratic formula which can be used when
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^{2}}-4ac }{2a}

a=1
b=8
c=3

x=\frac{-8+/- \sqrt{8^{2}-4(1)(3)} }{2(1)}
x=\frac{ -8+/- \sqrt{64-12} }{2}
x=\frac{ -8+/- \sqrt{52} }{2}
x=\frac{ -8+/- 2 \sqrt{13} }{2}
x=-4+/- \sqrt{13}

x=-4+ \sqrt{13} or x=-4- \sqrt{13}
aprox x=-7.60555 or x=-0.394449
