How To Determine The Discriminant of a Quadratic Equation
Discriminant review (article) [1]
– Worked example: quadratic formula (negative coefficients). The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac
The is the part of the quadratic formula under the square root.. The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation.
– A discriminant of zero indicates that the quadratic has a repeated real number solution.. – A negative discriminant indicates that neither of the solutions are real numbers.
A Complete Guide to the Discriminant of Quadratic – mathsathome.com [2]
The discriminant is the part of the quadratic formula found within the square root. For a quadratic of the form a𝑥2 + b𝑥 + c, its discriminant is b2 – 4ac
The discriminant, b2 – 4ac is represented by the delta symbol, Δ.. The discriminant formula is Δ = b2 – 4ac, where a is the coefficient of 𝑥2, b is the coefficient of 𝑥 and c is the constant term of a quadratic.
We substitute the values of a = 1, b = 5 and c = 2 into the formula for the discriminant, b2 – 4ac.. The discriminant is important because it tells us how many solutions any quadratic equation has.
Discriminants and determining the number of real roots of a quadratic equation [3]
A discriminant is a value calculated from a quadratic equation. It use it to ‘discriminate’ between the roots (or solutions) of a quadratic equation.
Note: This is the expression inside the square root of the quadratic formula. If the discriminant is greater than zero, this means that the quadratic equation has two real, distinct (different) roots.
If the discriminant is greater than zero, this means that the quadratic equation has no real roots.. Therefore, there are no real roots to the quadratic equation 3×2 + 2x + 1.

[Solved] Which of the following statements are correct? (A) Internal [8]
(A) Internal reliability is described as the consistency of a measure taken at two different points of time.. (B) A distribution is random walk if it has a mean of 0 and variance of 1.
(D) Normal distribution cannot be applied to real life situations.. (E) Factor Analysis supersedes multiple discriminant analysis.
– Internal consistency reliability defines the consistency of the results delivered in a test, ensuring that the various items measuring the different constructs deliver consistent scores.. – There are three main techniques for measuring internal consistency reliability, depending upon the degree, complexity, and scope of the test
