so, what is the standard form? If you can't get that, you're hosed.
Maybe I have to switch sides so it might be t^2-4t+8=0. Please help me more!!!! :(
Unless you make an error in the "switching"
0=8+4t-t^2 ----> t^2 - 4t - 8 = 0
hint: use the formula, or complete the square
0=8+4t-t^2 ----> t^2 - 4t - 8 = 0
