How to calculate the discriminant of a quadratic equation?

The discriminant of a quadratic equation refers to the value obtained by multiplying the coefficient of the square term by the coefficient of the square root term. It's often symbolized by the letter D. As an example, take the equation which has a discriminant of The discriminant for this equation is equal to

How to solve quadratic equation discrim

The discriminant of a quadratic equation is the square of the coefficient of the second-degree term. If the discriminant is zero, the equation has no solutions. If the discriminant is a positive number, there are two solutions. If it is a negative number, there are no solutions.

How to calculate the discriminant of a quadratic equation given the roots?

If you know the roots of a quadratic equation, you can use the discriminant to find the equation. This works because the discriminant is a function of the roots of the equation.

How to find the discriminant of a quadratic equation?

If the quadratic equation has two roots, these roots are called the solutions for the equation. We will use the discriminant to check which roots are possible. Let be the roots of the quadratic equation. The discriminant is defined as follows: where a is the coefficient of the square term and b is the coefficient of the first term.

How to calculate the discriminant of quadratic equation?

The discriminant of a quadratic equation is defined as the square of the sum of the roots. The discriminant can be used to determine if a quadratic equation has solutions. If the discriminant equals zero, then there are no solutions. If the discriminant is positive, then there are two solutions, and if it is negative there are no solutions.
