Hi,
3x² - x + 20 = 0 can be solved by the quadratic formula:
x = ( -b ± √(b² - 4ac))/(2*a)
x = ( -(-1) ± √((-1)² - 4(3)(20)))/(2*3)
x = ( 1 ± √(1 - 240))/(6)
x = ( 1 ± √(- 239))/(6)
x = ( 1 ± i√( 239))/(6)
So the answers are:
.........._____
1 ± i√( 239)
-----------------
.......6
I hope that helps!! :-)

using quadratic formula, since it won't factor,
x = 1/6 ± â(1 - 4•3•20) / 6
x = 1/6 ± â-239 / 6
x = (1 ± iâ239)/6
