If a resistor of R ohms is connected across a battery of E volts with internal resistance

Question:

If a resistor of R ohms is connected across a battery of E volts with internal resistance r ohms, then the power (in watts) in the external resistor is E²R P = (R + r)²

If E and r are fixed but R varies, what is the maximum value of the power?
