Introduction to Discriminant Calculator
The online discriminant calculator is an online tool that is made to find the nature of roots of a quadratic equation. It uses the discriminant formula and the values of coefficients of quadratic equations to find the nature of roots. It is a simple way that can tell whether the roots are real or not.
In algebra, the quadratic equations are solved to find their solutions but the solution cannot tell you its nature. Therefore, the discriminant calculator is introduced to you so that you can find the nature of roots of the quadratic equations without solving it.
Formula used by discriminant and nature of roots calculator
The discriminant is a part of the quadratic formula to solve any polynomial of degree 2. The quadratic formula is
$$ X=\frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $$
This is the same formula used by quadratic formula calculator with steps.
And the formula of discriminant is
$$ ∆\;=\;b^2\;-\;4ac$$
Where a and b are the coefficients of independent variables x and c is the constant. It is a smart and easy way to find the nature of roots of the equation ax2 + bx + c = 0. The discriminant nature of roots calculator uses this formula to determine the nature of the roots. So, it enables you to identify the nature of an equation without solving it.
Nature of Roots
For a quadratic equation ax2 + bx + c = 0, the nature of roots can be determine as
- If ∆ < 0, then the roots are imaginary.
- If ∆ > 0, then the roots are real and unequal.
- If ∆ ≥ 0, then the roots are real and equal.
- If ∆ = 0, then the roots are equal and real.
