    Square both sides to undo that radical. :) You are trying to get to the t so undo the things around it.

    In order to solve for t u have to isolate t. 1.Square both sides 2.Add 5 to both sides.

    \[\sqrt{t-5} = 2\] \[t-5 = 4\] \[t = ?\]

    yup right:) good work.:) Nw bring all the terms to one side. Then use quadratic formula to find x. Quadratic formula is \[x=\frac{ -b\pm\sqrt{b^2-4ac} }{ 2a }\]
