Question

Please help!! How do I do this? I don't understand the question. I'll write it out since I can't upload a pic for some reason.

Answer 1

When b^2 -4ac >0 you get rational answers.  I suppose you could use factoring as well as the quadratic formula.
when b^2 -4ac =0  You get one answer.  Okay it is till technically "two" answers but you say BOTH values of x = whatever.
when b^2 -4ac <0 the answers are complex (imaginary) and have the value of "i" somewhere in them.  For example the answers might be 2 + 2i that kind of thing
