The inverse operation is a cubed root. It is a square root symbol with a small 3 to the left of the radical. The cubed root of x is a number, when cubed, gives x. For example, .
Check the picture below.
thus is at 0 = -16t² + 96t +640,
well, clearly it can't be a negative value for the elapsed seconds, so it can't be -4.
