The zero product property states

If ab=0, then a=0 or b=0.

If ab=-1, then a=-1 or b=-1.

If ab=0, then a=1 or b=1.

If ab=1, then a=1 or b=1.

When completing the quardratic formula, you get a positive prime number as a radicand. This means that

you will not have a solution.

you will have exactly one solution.

you could easily graph the parabola to find the solution.

you have an irrational answer as a solution.
