I FORGOT TO ADD THIS!!! This is to solve a quadratic equation. state if there is no real roots. what are the real roots? does that mean state if there is no answer?

psymon · Answer

basically the root sign is a radical. And for this problem you first need to move the -3t and the + 4 to the other side of the equal sign and then yeah, factor. 
And real as in possible by normal mathematical standards. For example:
$$\sqrt{-1}$$ wouldn't be what you would call real, since you cannot square root a negative number.

Like this would be an example of a problem with no "real" solutions:
$$x ^{2}+4 = 0$$
$$x ^{2}=-4$$
$$x=\pm \sqrt{-4} $$ This would give an imaginary solution, not a real one :3
