I need help with this question

5. (3 marks). If a resistor of r ohms (x 2 0) is connected across a battery of E volts with internal resistance r ohms, then the power (in watts) in the external resistor is P(x) = E- I (Itr)2 If E and r are fixed positive constants, find the absolute maximum value of the power. Note: for full marks, explain why you know your answer is the absolute marimum
