Question

If the discriminate of a quadriatic equation is 4, how many solutions does the equation have?

Answer 1

two solutions

Explanation:

If you have a discriminant value greater than zero (not zero and not negative), you're gonna have two solutions. For zero discriminant, one solution. For negative discriminant, no solutions at all.

Make sure you remember this. It will save you from solving a quadratic equation which has no solutions.
