1. Hi can someone help me with this question:
t^3-3t^2+4=0
Solve for t
The answer is t=-1 or 2 but I'm not sure how to get that

the first root you find has to be by inspection im pretty sure, i cant think of any other way to factor it.

then use long division and get a quadratic which you can easily factor.
