Quadratic equation w/ sqrt! (simplifying solution)

[Guest]

How in the world do I solve this with square roots?

(please excuse the crudeness)

I solved the problem as far as this:

but I'm not sure if I did that right...did I? and how do I solve it from here?

IF that's 3 times sqrt(3)^2 - 4(2)(-6), then you get 9 + 48 = 57: so that part is correct.

It's almost always best to provide the tutors with the original exercise. Was the original question to "Solve 2x² + 3^3/2x - 6 = 0 using the Quadratic Formula"?

Thank you.
