What Is Discriminant?
The quadratic formula is $$x= \frac{-b \pm \sqrt {b^2-4ac}}{2a}$$
It can be found by using the quadratic formula to find a discriminant function. It is represented as b²-4ac and the discriminant can be zero, positive, or negative. This indicates whether there will be no solution, one solution, or two solutions.
Integration By Parts Calculator
Observe the following characteristics of discriminant algebra’s formula:
- A zero discriminant indicates that there are repeated real number solutions to the quadratic;
- In the case of a negative discriminant, neither of the solutions are real;
- The quadratic equation has two distinct solutions that are real numbers for a positive discriminant.
The following quadratic equation illustrates to the students how to determine the discriminant by showing a variety of solutions.
For example, the given quadratic equation is $$6x^2 + 10x – 1 = 0$$
From the above equation, it can be seen that:
a = 6, b = 10, c = -1
When the numbers are applied to discriminant analysis – $$b^2 − 4ac$$
$$= (10)^2 – 4 (6) (-1)$$
$$= 100 + 24$$
$$= 124$$
The discriminant being a positive number, there are two solutions to the quadratic equation.
Relationship Between Roots and Discriminant
The quadratic formula not only generates quadratic equation solutions but also tells us about the nature of the solutions. When we consider the discriminant, or the expression under the radical, $$b^2-4ac$$, it tells us if the solutions are real numbers or complex numbers and how many of each type we can expect.
Let us explore how the discriminant affects the evaluation of $$\sqrt {b^2-4ac}$$ in the quadratic formula and how it helps to determine the solution set.
If $$b^2-4ac >0$$
Here,
a, b, c = real numbers
a ≠ 0
discriminant = positive
If the radical is positive, then the number underneath it will be positive. Since you can always find the square root of a positive number, calculating the quadratic formula will yield two real solutions (one by adding the positive square root and one by subtracting it).
If $$b^2-4ac =0$$
Here,
a, b, c = real numbers
a ≠ 0
discriminant = zero
Then you will take the square root of 0, which is 0. Since adding and subtracting 0 both give the same result, the “±” portion of the formula does not matter. There will be only one solution.
If $$b^2-4ac <0$$
Here,
a, b, c = real numbers
a ≠ 0
discriminant = negative
If the radical is negative, the value underneath it will be negative. There are no real solutions to finding the square root of a negative number because you cannot use real numbers. It is possible, however, to use imaginary numbers. Then you will have two complex solutions, one by adding the imaginary square root and one by subtracting it.
If $$b^2-4ac >0 \ as\ a\ perfect\ square\ as\ well$$
Here,
a, b, c = real numbers
a ≠ 0
discriminant = positive and perfect square
Therefore, the roots of the quadratic equation are unequal, real, and rational.
Things to Remember While Using Quadratic Formula
- It is absolutely crucial that the equation is arranged correctly in order to arrive at a solution.
- Ensure that 2a and the square root of the entire (b² − 4ac) are placed at the denominator.
- Keep an eye out for negative b². This cannot be negative, so be sure to change it to positive. The square of either positive or negative is always positive.
- The +/- should remain. Be aware of two solutions.
- The number will have to be rounded on a certain number of decimal places when using a calculator.
