The discriminant
Polynomials
It is possible to determine how many solutions a quadratic equation has without actually solving the entire equation. In the quadratic formula, what is under the square root is referred to as the discriminant (referred to by the symbol delta) and can be used to determine how many solutions a quadratic has.
\[\Delta =b^{2}-4ac\]
\[\Delta =b^{2}-4ac\]
