Introduction to Discriminant Calculator
Discriminant calculator is an online digital tool that is used for finding the discriminant of roots of quadratic equations using its coefficient values. Our tool computes the quadratic equation formula to find whether the nature of the root is real or imaginary in less than a minute.
What is Discriminant?
Discriminat is the component in the quadratic equation that find discriminant of the nature of roots in quadratic equation.
Resultantly, it gives real roots or imaginary or maybe it gives them both real or imaginary roots. For Discriminant D or Δ symbol is used in the quadratic equation formula for finding roots.
Rules Followed by Nature of Roots Calculator:
The discriminant calculator uses the following discriminant rule of the quadratic equation to find the root value.
$$ ax^2 + bx + c \;=\; 0 \; \; , b^2 − 4ac $$
Here,
a,b,c are the coefficients of the quadratic equation
Stepwise Evaluation Process of Discriminant Finder
Nature of roots calculator uses a quadratic equation formula to find out the polynomial roots of the given equation quickly and easily. You can get the solution of various types of polynomial coefficients discriminant roots in a couple of seconds.
When you enter the polynomial coefficients in the discriminate calculator, it starts to identify the given data.
After identification, the discriminant calculator finds the quadratic equation and then compares the given equation with its standard form of quadratic equation to determine the coefficients first.
After that, it substitutes the coefficients in the discriminant formula as b2-4ac to find the discriminant roots. There are three cases through which it tells whether a given equation gives real or imaginary root values.
Case 1: When b2 - 4ac >0
When you add the coefficient in the discriminant math calculator, if its result is a positive number then the quadratic equation gives real or positive but unequal roots.
Case 2: When b2 -4ac <0
When you add the coefficient in the nature of roots calculator, if its solution gives a negative number then the quadratic equation gives imaginary or negative roots.
Case3 : When b2 - 4ac =0
When you add the coefficient in the discriminant calculator, if its result is equal to zero then the quadratic equation gives real and equal positive roots.
Find the Discriminant - An Example
To get more clarity about this concept let's observe an example of a quadratic equation along with its solution in detail. Now you would know how to calculate discriminant and understand the results of the discriminant finder.
Example 1:
Determine the discriminant of the following equation using the formula b2-4ac.
$$ x^2 + 5x + 4 \;=\; 0 $$
Solution:
From the above equation,
$$ a \;=\; 0, b \;=\; 5 \;and\; c \;=\; 4 $$
Therefore,
$$ b^2 - 4ac \;=\; (5)^2 - 4(1)(4) \;=\; 25 - 16 \;=\; 9 $$
When the discriminant is than 0 then there are two different real roots.
Example 2:
Determine the discriminant of the following equation using the formula b2-4ac
$$ -3x^2 + 6x - 3 \;=\; 0 $$
Solution:
From the above equation,
$$ a \;=\; -3, \; b \;=\; 6 \;and\; c \;=\; -3 $$
$$ b^2 - 4ac \;=\; (6)^2 - 4(3)(-3) $$
$$ \;=\; 36 -36 \;=\; 0 $$
Example 3:
Determine the discriminant of the following equation using the formula b2-4ac.
$$ -x^2 + 3x - 3 \;=\; 0 $$
Solution:
From the above equation
$$ a \;=\; -1, \; b \;=\; 3 \;and \; c \;=\; -3 $$
Therefore,
$$ b^2 - 4ac \;=\; (3)^2 - 4(-1)(-3) $$
$$ \;=\; 9 - 12 \;=\; -3 $$
So, there are no real roots and the discriminant is less than zero. There are exactly two distinct imaginary roots.
