A plug is removed from a trough to drain the water. The volume, in gallons, in the trough after it has been unplugged can be modeled by the expression 10x2 − 11x + 3, where x is the time in minutes. Choose the appropriate form of the expression that would reveal the time, in minutes, when the trough is empty. A)10(0)^2 − 11(0) + 3
B) (5x − 3)(2x − 1)
C)10(x − 3)2 − 1
D)10(x − 1)2 − 3
