📐 Factoring Trinomials Calculator

Factor trinomials of the form ax² + bx + c

ax² + bx + c

How to Use This Calculator

1

Enter Coefficients

Type a, b, and c for ax² + bx + c.

2

Click Factor

See the diamond solution to help factor the trinomial.

Method

Use the diamond problem to find factors

Example: Factor x² + 7x + 12

Diamond: top = 7, bottom = 1 × 12 = 12

Find two numbers: m + n = 7, m × n = 12

Solution: m = 3, n = 4 (or vice versa)

Factor: (x + 3)(x + 4)

About Factoring Trinomials Calculator

The Factoring Trinomials Calculator helps factor quadratic trinomials using the diamond method. This finds two numbers that solve the diamond problem, which are the key to factoring the trinomial into binomials.

When to Use This Calculator

  • Factoring Practice: Learn to factor quadratics
  • Homework Help: Solve factoring problems

Tips

  • Works best when a = 1 (simple case)
  • Check if it's a perfect square trinomial first
  • Practice with different examples to learn patterns

Frequently Asked Questions

What if a ≠ 1?

For coefficients other than 1, use the diamond method to find factors of a×c that add to b, then group and factor by grouping.

What if no factors are found?

The trinomial may not factor over integers, or you may need to use the quadratic formula to find solutions.
