drwls,
Put it in the form ax^2 + bx + c = 0
If you cannot factor it easily into two momialsw, then use this "quadratic equation" for the two solutions.
x = [b +/ sqrt(b^24ac)]/2a
+/ means "plus or minus"
"sqrt" means "square root of"
They should me teaching you thisw equation as part of your algebra course.
