Question

A quadratic equation of the form 0=ax^2+bx+c has a discriminant value of -16. How many real numbers solutions does the equation have?

Answer 1

Answer: 0

Explanation:

The disciminant \Delta tells you how many real solutions a quadratic equation has, depending on its sign:

\Delta>0\implies\text{2 solutions}\\\Delta=0\implies\text{1 solution}\\\Delta<0\implies\text{no solutions}
