Question 41233: Addition seems simple enough to me, but the minus/negative numbers confuse me on factoring.
x2 - 6x - 3 = 0
Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
This one cannot be factored, so use the quadratic formula
x^2 - 6x - 3 = 0
for which we get
x = (6 ± sqrt(36 + 12)) / 2
x = (6 ± sqrt(48)) / 2
x = (6 ± 4*sqrt(3)) / 2
x = 3 ± 2*sqrt(3)
