FAQ
The discriminant of a quadratic equation ax2 + bx + c = 0 is in terms of its coefficients a, b, and c. i.e., Δ OR D = b2 − 4ac.
I.e., it discriminates the solutions of the equation (as equal and unequal; real and nonreal) and hence the name "discriminant". It is usually denoted by Δ or D. The value of the discriminant can be any real number (i.e., either positive, negative, or 0).
The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
In algebra, the discriminant, represented as uppercase delta (Δ), is a value calculated from the coefficients of a quadratic equation. It is used to determine the nature of the solutions to the equation. If Δ is greater than zero, the equation has two distinct real roots.
For the quadratic equation ax2 + bx + c = 0, the expression b2 – 4ac is called the discriminant. The value of the discriminant shows how many roots f(x) has: - If b2 – 4ac > 0 then the quadratic function has two distinct real roots. - If b2 – 4ac = 0 then the quadratic function has one repeated real root.
Solution: As given, quadratic equation 3√3x2+10x+√3=0. Thus, discriminant of the given quadratic equation is 64.
To find the discriminant given the quadratic equation f(x)=ax^2+bx+c, simply record the values of a, b, and c and then substitute them into the discriminant formula: d=b^2-4ac. This will give the value of the discriminant. This also tells the number of roots and whether or not the roots are real or imaginary.
The given equation is of the form ax2 + bx + c = 0 where a = 2 b = – 4 andc = 3. Therefore the discriminantb2 – 4ac = – 42 – 4 × 2 × 3 = 16 – 24 = – 8 < 0So the given equation has no real roots.

The formula for the discriminant is simple but powerful: D=b2−4ac. The discriminant is an important term to know when dealing with quadratic equations.Essentially, the discriminant is simply this expression: b2-4ac. Using the square root property it is possible to solve any quadratic equation written in the form. The discriminate formula is b squared minus four ac for quadratic equation in standard form ax squared plus bx plus c. The discriminant tells you about the "nature" of the roots of a quadratic equation given that a, b and c are rational numbers. The discriminant is positive, so there are two real solutions. The formula derives from the quadratic formula. The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant is calculated using the formula D=b2−4ac.
