2. Click the “Calculate” button.
3. View the results below the calculator.

Formula & Methodology

The cubic function can be represented as:

f(x) = ax³ + bx² + cx + d

The roots of the function are the zeros we’re given. To find the coefficients, we use the following system of equations:

• x1 + x2 + x3 = -b/a
• x1*x2 + x2*x3 + x3*x1 = c/a
• x1*x2*x3 = -d/a
