The quadratic equation calculator is an extremely useful online calculator, which solves any given quadratic equation by using quadratic formula

We know, that for a quadratic equation ax² + bx + c = 0, where a ≠ 0, the quadratic formula is:

After inserting values of a, b and c and solving the quadratic equation using the quadratic formula explained above, we get two values:

These two values of x – x₁ and x₂, which are calculated from the quadratic formula, also known as roots of quadratic equation. These two roots are the output of quadratic equation calculator

Hence, Quadratic Equation Calculator calculates roots of a Quadratic equation

◾ If b² – 4ac > 0, then √b2 − 4ac  is real; in this case Quadratic equation calculator provides us a solution of two real and distinct roots.

◾ If b² – 4ac = 0, then √b2 − 4ac  is also zero; in this case Quadratic equation calculator provides us a solution of real and equal roots.

◾ If b² – 4ac < 0, then √b2 − 4ac  is imaginary number; in this case Quadratic equation calculator provides us a solution of imaginary roots.

◾ If b² – 4ac is a perfect square, then √b2 − 4ac  is a rational number; in this case Quadratic equation calculator provides us a solution of rational roots, else Quadratic equation calculator provides us a solution of irrational roots.

Step 1 - At the first step in using Quadratic Equation calculator , we have to rearrange the Quadratic Equation we have, into what is known as Standard Form of Quadratic Equation, which is represented as ax² + bx + c = 0

So, Let's suppose we have to solve a quadratic equation which is currently in the form of

x² -11x = -24

So we rearrange this equation, so that is represented in the standard form ax² + bx + c = 0. Hence,

x² - 11x = -24 is now equal to x² - 11x + 24 = 0.

Now the quadratic equation has been successfully converted into standard form

Step 2 - Now, to use our Quadratic Equation calculator, we have to input coefficient a, b and c in the calculator. So our next step is to find coefficient a, b and c. So we compare our derived equation above in standard form x² - 11x + 24= 0 with ax² + bx +c = 0.

Hence, we get

a = 1,
b = -11,
c = 24
