How to determine the discriminant of a quadratic equation?

The discriminant can be found by multiplying the coefficients of each term by their negatives. If you have two terms whose coefficients are both positive, then take the square root of their product. If you have two terms whose coefficients are both negative, then take the negative of their product. If you have two terms whose coefficients are both negative and you want a positive discriminant, then square the absolute value of the coefficient of one term, then add that to the square of the coefficient of the other term.

How to find the discriminant of a quadr

The discriminant of a quadratic equation is a number that helps us determine whether a quadratic equation has solutions. In our example, the discriminant of the quadratic equation is $49$, so this equation has no solutions. The discriminant of is $-0.2$, so this equation has two solutions, which can be found at $(-0.2,0)$ and $(0,0)$.

How to determine the discriminant of a quadratic equation with variables?

This is a question that is often asked by high school and undergraduate students who are learning quadratic equations. If the discriminant equals 0, the graph of the equation will have a vertex at the origin. Quadratic equations with a discriminant that equals zero are called degenerate.

How to find discriminant of a quadratic equation?

The discriminant of a quadratic equation is the square of the coefficient of the square term. If the discriminant is positive, the equation has no real roots, and if the discriminant is negative, the equation has two real roots. If the discriminant equals zero, the equation has either two equal roots or no roots.

How to determine discriminant of a quadratic equation?

The discriminant is used to find the number of roots of a quadratic equation. If the equation has two roots, the discriminant will be positive. If the equation has no roots, the discriminant will be negative. If the equation has one root, the discriminant will be zero.
