I am assuming that "an algebra equation" refers to a quadratic equation and not a higher polynomial.
For a quadratic equation of the form y = ax^2 + bx + c, where a, b and c are real numbers and a is non-zero, the discriminant is b^2 – 4ac.

Why the discriminant of a quadratic is useful in algebra?
Because the square root of the discriminant is a component of the roots of the equation.
How many discriminant did this quadratic equation have -4j2 3j-280?
A quadratic equation has one discriminant.
What is the discriminant for this equation x2-3x plus 5 equals 0?
The discriminant is -11.
What are quadratic equations with real roots?
If the discriminant of the quadratic equation is zero then it will have 2 equal roots. If the discriminant of the quadratic equation is greater than zero then it will have 2 different roots. If the discriminant of the quadratic equation is less than zero then it will have no roots.
What type of equation is b2-4ac?

Why the discriminant of a quadratic is useful in algebra?
Because the square root of the discriminant is a component of the roots of the equation.
What do you do if you have a negative discriminant in a quadriatic equation?
By calculating the discriminant of the equation and if it's negative the equation will have no solutions
If the discriminant of an equation is 0?
If the discriminant of a quadratic equation is zero then it has two identical roots.
How many discriminant did this quadratic equation have -4j2 3j-280?
A quadratic equation has one discriminant.
If the discriminant of a quadratic equation is -4 how many solutions does the equation have?
If the discriminant of a quadratic equation is less then 0 then it will have no real solutions.
What is the discriminant of the equation X2-10?
12
What can the discriminant tell you about a quadratic equation?
It can tell you three things about the quadratic equation:- 1. That the equation has 2 equal roots when the discriminant is equal to zero. 2. That the equation has 2 distinctive roots when the discriminant is greater than zero. £. That the equation has no real roots when the discriminant is less than zero.
What does the discriminant tell you?
The discriminant tells you how many solutions there are to an equation The discriminant is b2-4ac For example, two solutions for a equation would mean the discriminant is positive. If it had 1 solution would mean the discriminant is zero If it had no solutions would mean that the discriminant is negative
If the discriminant of an equation is zero then?
The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.
What is the answer to the discriminant equation of -4.9 plus 4.3t plus 10?
A discriminant is based on the differences between roots of an equation. A linear equation, such as the onle in the question, has only one root and therefore cannot have a discriminant.
What is the discriminant of the equation 4x2 plus 1 equals 9x-2?
The discriminant is 33.
What is the discriminant for this equation x2-3x plus 5 equals 0?
The discriminant is -11.
