Solve by using the quadratic formula.
x^2 + 6x + 6 = 0
I am having problems using the quadratic formula to get the right answer. Can someone show me the steps that I use? Thanks.
Quadratic formula -b(plus or minus)squareroot(b^2-4ac) all over 2a
so you'd plug in -6(plus or minus)squareroot((6^2)-(4(1)(6)) and divide the -6 plus /\ that by 2. and then do -6 minus /\ that by 2. and you get your two solutions
-3 + or - 2sqrt 3
