Answer 2

Answer:

Δ = $b^{2}$ – 4ac

Step-by-step explanation:

The discriminant formula is Δ = $b^{2}-4ac$, where a is the coefficient of $x^{2}$, b is the coefficient of and c is the constant term of a quadratic. For example, calculate the discriminant of y = $x^{2}$ + 3 + 2. We have one $x^{2}$. The coefficient of $x^{2}$ is 1, the coefficient of x is 3 and the constant is 2. Here the discriminant is 1.
