Formula used
The quadratic formula finds the roots r1 and r2, so ax² + bx + c = a(x − r1)(x − r2).
Example: x² − 5x + 6 = (x − 2)(x − 3).

FAQ
Frequently asked questions
What if the roots aren't whole numbers?
The factored form still applies, just with decimal roots shown.
What if the roots are complex?
The expression can't be factored over the real numbers, and the calculator will note this.
Does this work for non-quadratic expressions?
No, this tool specifically factors quadratics (degree 2) using their two roots.
How is factoring useful?
It reveals the values of x that make the expression equal zero.
