Okay, algebristas,* different equations can have different numbers of solutions. Right now, we are only counting solutions from the real numbers. Some equations have solutions that are imaginary numbers, but we'll get to those later. No, you don't need to send us a Thank You card. Your words are enough.
*You know, people who serve mathuccinos. Alternatively, you.

Diophantus was a famous mathematician who's sometimes called "The Father of Algebra." Although with the way he got around, who wasn't he the father of? #ancientgossip
Anyway, D-man only liked positive rational solutions to equations. He would probably call a lot of the equations we will be solving "absurd" since they have negative solutions. It's hard to blame him, though—after all, there's no such thing as a negative child. (He wishes. Oh, burn.)
