What is Factoring?

Factoring is the process of breaking a number or an expression down into smaller pieces that multiply together to give you the original value. With whole numbers, that means finding which numbers divide evenly into another number

Example,

• 4 and 6 are both factors of 24, since 4 x 6 = 24.

Formula

1) Difference of squares

Formula: a² – b² = (a – b)(a + b)

Example:

• x² – 25 = (x – 5)(x + 5)
• because 25 = 5²

2) Sum of cubes

Formula: a³ + b³ = (a + b)(a² – ab + b²)

Example:

• x³ + 8 = (x + 2)(x² – 2x + 4)
• because 8 = 2³

3) Difference of cubes

Formula: a³ – b³ = (a – b)(a² + ab + b²)

Example:

• x³ – 64 = (x – 4)(x² + 4x + 16)
• because 64 = 4³

4) Quadratic formula

Formula: x = (-b ± √(b² – 4ac)) / 2a

Example: Solve x² – 5x + 6 = 0

Here,

• a = 1
• b = -5
• c = 6

Substitute into the formula:

• x = [ -(-5) ± √((-5)² – 4(1)(6)) ] / 2(1)
• x = [ 5 ± √(25 – 24) ] / 2
• x = [ 5 ± 1 ] / 2

So the two solutions are:

• x = (5 + 1)/2 = 3
• x = (5 – 1)/2 = 2

Answer:

• x = 2, 3

About TankCalculator’s Factoring Calculator

Our factoring calculator handles two distinct kinds of factoring problems through separate tabs: Number Factors and Polynomial Factoring.

The Number Factors mode will accept an integer and then determine the complete set of factors, factor pairs, prime factors, primality of the integer (whether it is prime or composite), and whether it is even or odd. In addition to that, it gives you the sum and product of factors and also determines the greatest and smallest factors.

The Polynomial Factoring feature is designed to factor a broad array of polynomials, including linear to quartic or biquadratic polynomials. The feature looks for patterns that can be used for factoring like the difference of squares, sum or difference of cubes, perfect square trinomial, and factoring by grouping, or uses the rational root theorem or the quadratic formula in case there is no recognizable pattern.

Benefits of Using TankCalculator’s Factoring Calculator

Factoring by hand is a fundamental skill worth learning, but it’s also easy to make small mistakes — missing a factor pair, misapplying the AC method, or overlooking a pattern like difference of squares. This calculator catches those details automatically, which saves time and helps confirm whether your own manual work is on the right track.

With regard to dealing with polynomials, the solutions for polynomials enable students to work on the logic process and not just give the solution without any logical explanation.

If anything to do with integers, there will be a need for listing all the factors, the factor pairs, the sum of the divisors, and the prime factorization of the number all at once rather than simply having to check if the number is prime or not – this is particularly helpful in cases of mathematical competitions and number theory.
