This tool helps you find the zeros of any given function quickly and easily.

## How to Use the Find the Zeros of the Function Calculator

This calculator helps you find the zeros (roots) of a quadratic function of the form *ax² + bx + c = 0*. To use the calculator, enter the coefficients ‘a’, ‘b’, and ‘c’ into the respective input fields and click the “Calculate” button.

### How It Calculates the Results

The calculator uses the quadratic formula: *x = [-b ± sqrt(b² – 4ac)] / 2a*. It first calculates the discriminant (*b² – 4ac*). Based on the value of the discriminant:

- If the discriminant is greater than zero, there are two real roots.
- If the discriminant is equal to zero, there is one real root.
- If the discriminant is less than zero, there are no real roots.

### Limitations

This calculator only works for quadratic equations (degree 2). Ensure that the coefficients entered are valid numbers. If you enter non-numeric values or leave any field empty, the calculator will prompt you to enter valid numbers.
