If a planet were to have three suns, not necessarily the strenght of ours, what would that planet be like? I was thinking desert-ish but I'm not sure.

Also, what is your best guess as to what would happen if a star went supernova (or some sort of equally large explosion) inside a black hole? Would the two counter act one anothers affect, possibly create a new something (star, planet, etc.) in it's place?

I know it's fiction so I can technically make up whatever I want, but I want it to be semi-realistic. You don't want the reader to lose interest because what you've done sounds unplausable.

Thanks for your input!!

if the equation is x squared + 4x + 8=0 and the instructions say "find the zeros," how would you do that?
also, when you are "finding the zeros" of an equation, what exactly are you doing? like, are you finding all the numbers that will make your equation equal to 0? or what?
thanks.
