Question 1

What is a Complex Roots Calculator?

Accepted Answer

Complex roots occur when a polynomial equation has no real solutions — the discriminant is negative. The roots come in conjugate pairs: a + bi and a − bi, where i = √(−1).

Question 2

How does the Complex Roots Calculator work?

Accepted Answer

For ax² + bx + c = 0: roots = (−b ± √(b²−4ac)) / 2a Then: When b²−4ac < 0: roots are complex Then: √(negative) = i × √(|negative|) Then: Complex roots always appear as conjugate pairs.

Question 3

Can you give an example of how to use the Complex Roots Calculator?

Accepted Answer

Example: Input x² + 4 = 0 gives a result of x = ±2i.

Question 4

Is the Complex Roots Calculator free to use?

Accepted Answer

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
