When we solve for x and get two answers do we state this as, for example, x = -2 OR x=3. Or do we state it as x = -2 AND x=3?
I'm new to quadratic equations, obviously, and I've heard someone say, 'Or', another say, 'And', and yet another just put a comma between the two answers.

Thanks.
So one answer will work, when plugged in to the equation. And one won't work?

No. Both will.

both sol'ns work
but x cant be 2 values AT THE SAME TIME
so x = -2 OR x = 3
but both are valid sol'ns
