What are the factor formulas?
Factoring Formulas
- Factoring Formula 1: (a + b)2 = a2 + 2ab + b.
- Factoring Formula 2: (a – b)2 = a2 – 2ab + b.
- Factoring Formula 3: (a + b) (a – b) = a2 – b.
- Factoring Formula 4: (x + a) (x + b) = x2 + (a + b) x + ab.
- Factoring Formula 5: (a + b)3 = a3 + b3 + 3ab (a + b)
- Factoring Formula 6: (a – b)3 = a3 – b3 – 3ab (a – b)
How do you factor in math?
A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product. There are two methods of finding factors: multiplication and division.
