Question

Can someone help me solve this equation?
\(-16t^2 +~20t~+~5~=~0\)
I need to write the solution in simplified radical form. If it helps, the dominant is 720.

Answer 1

Well do you know how to find the solution? Do you know about the quadratic formula?

Answer 2

Yes, I know of the quadratic formula. I already know that the dominant is 720.

Answer 3

So it would look something like this:
\(\Large t =\) \(\Large-20 \pm \sqrt{720} \over\Large 2 \Large\times -16\)
