Ok. That mean Part B if cell A is 3VDC and cell B is 1.5VDC, that mean the bulb will come on and with both 1.5VDC the bulb will remain un-powered because of no potential different?
Homework Statement
Given a 24VDC Generator, a 12VDC Battery(Discharged), a bulb(no rating yet), pieces of thick wires(unlimited length you can use)
You need the 24VDC generator to charge the 12VDC battery, but direct will damage the battery. What should I do with the bulb? I need to build a...

hmm
HallsofIvy,
this is mine error?
The factors are (X-1)(X-2)(X+4)
NO, they aren't. That's your error
Should it be The factors are (X-1),(X-2),(X+4)? put commas between each factor?
Yeah i found that i accidentally wrote X²+x-8 without the 2 inside.
HallsofIvy, maybe you right over here that
X²+2X-8=(X-2)(X+4), or i should write
X²+2X-8=0
(X-2)(X+4)=0?

Trying to ask my method of doing the question is correct or not? Try check is there any mistake please? I am beginner.
