I need help quick please.
1. Find all the values of H such that the equation 3x2-2x + H=O has imaginary roots.
2.When a Current, C flows through a given electrical circut, the power, W of the circuit can be determined by the formula W= 120C - 12C2. What amount of current supplies the maximum power. And what is the maximum power that can be delivered in this circuit.
the 2 after the c and X means squared sorry don't know how else to do it.
