help solving a problem

[relapse]

I'm suppose to solve this problem with any method, like completing the square, quad formula, etc..

3x^2 - 17x - 6 = 0

I used quad formula and got 17(square root of)361 over 6. i think this is wrong, is there an easier method to solve it with?

...and got 17(square root of)361 over 6

should be: and got [17 +- (square root of)361] over 6

properly typed: (17 +- sqrt(361)) / 6

What's sqrt(361) ?

You could have factored it: (x - 6)(3x + 1) = 0
