What are the steps to use the quadratic equation calculator?
Allcalculator.net's The quadratic equation is a polynomial with the highest exponent, which should be 2. The standard form of the quadratic equation is Ax2 + Bx + C = 0.
Here are the steps to use the quadratic equation calculator are:
- Enter the coefficients of the equation in the required input fields with the given statements.
- Click on the button to solve the quadratic equation to get the exact result
.
- In the final steps, you can find the result for the roots of the quadratic equation, which will be displayed in the output fields.
The basic quadratic formula is:
X = -b ± √b2 – 4ac / 2a
This above formula is used to solve all the quadratic equations where a ≠ 0 with a polynomial order of 2.
ax2 + bx + c = 0
Enter the equation for real and complex roots in the calculator to determine the discriminant (b2 – 4ac), which is less than, greater than or equal to 0.
- When b2 – 4ac = 0, there is no real roots
- When b2 – 4ac > 0, there are two real roots
- When b2 – 4ac < 0, there are two complex roots
What are the types of quadratic equations?
There are three types of quadratic equations which are discussed below:
Standard form
It is a quadratic equation which is given by ax^2 + bx + c = 0
where a, b, and c are constants and x is a variable.
Vertex form
The Vertex form of a quadratic equation is given by a*(x - h) ^2 + k
A h and k are constants, and (h, k) is the vertex of the parabola
Factored form
The factored form of a quadratic equation is given by a*(x - r1) (x - r2)
Where a, r1, and r2 are constants and r1 and r2 are the roots or solutions of the quadratic equation
