The four main types of factoring are the Greatest common factor (GCF), the Grouping method, the difference in two squares, and the sum or difference in cubes.
What is factorisation method example?
Factorisation is the process of reducing the bracket of a quadractic equation, instead of expanding the bracket and converting the equation to a product of factors which cannot be reduced further. For example, factorising (x²+5x+6) to (x+2) (x+3). Here, (x+2) (x+3) is factorisation of a polynomial (x²+5x+6).
What is the formula of factorization?
The general factorization formula is expressed as N = Xa × Yb × Zc. Here, X, Y, Z represent the factors of a factorized number.
What are the 5 rules of factoring?
- x2 – (r + s)x + rs = (x – r)(x – s)
- x2 + 2ax + a2 = (x + a)2 and x2 – 2ax + a2 = (x – a)2
- Difference of squares: a2 – b2 = (a – b)(a + b)
- Difference of cubes: a3 – b3 = (a – b)(a2 + ab + b2)
- a4 – b4 = (a – b)(a3 + a2b + ab2 + b3) = (a – b) [ a2(a + b) + b2(a + b) ] = (a – b)(a + b)(a2 + b2)

What is factorisation easy?
In Mathematics, factorisation or factoring is defined as the breaking or decomposition of an entity (for example a number, a matrix, or a polynomial) into a product of another entity, or factors, which when multiplied together give the original number or a matrix, etc.
How do you factorise Class 9?
Now, suppose p(x) is divided by (x − a), then quotient is g(x). By remainder theorem, when p(x) is divided by (x − a), then remainder is p(a). On dividing p(x) by (x − a), let g(x) be the quotient.
Why do we factorise in maths?
Similarly in algebra, factoring is a remarkably powerful tool, which is used at every level. It provides a standard method for solving quadratic equations as well, of course, as for simplifying complicated expressions. It is also useful when graphing functions. Factoring (or factorising) is the opposite of expanding.
What are the 6 types of factoring?
The lesson will include the following six types of factoring:
- Group #1: Greatest Common Factor.
- Group #2: Grouping.
- Group #3: Difference in Two Squares.
- Group #4: Sum or Difference in Two Cubes.
- Group #5: Trinomials.
- Group #6: General Trinomials.
What are the steps in factoring?
Step 1: Group the first two terms together and then the last two terms together. Step 2: Factor out a GCF from each separate binomial. Step 3: Factor out the common binomial. Note that if we multiply our answer out, we do get the original polynomial.
What is the factor of 36?
The factors of 36 are the numbers that divide 36 exactly without leaving any remainder. Thus, the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.

What does factorise mean in math?
Factorising is a way of writing an expression as a product of its factors using brackets. We do this by taking out any factors that are common to every term in the expression. Maths. Algebra.
How do you factor 5400?
- 1 × 5400 = (1, 5400)

How do you solve factorization problems?
To solve an quadratic equation using factoring :
- 1 . Transform the equation using standard form in which one side is zero.
- 2 . Factor the non-zero side.
- 3 . Set each factor to zero (Remember: a product of factors is zero if and only if one or more of the factors is zero).
- 4 . Solve each resulting equation.

What is factorisation class 4th?
Prime factorization is the process of finding the prime numbers, which are multiplied together to get the original number. For example, the prime factors of 16 are 2 × 2 × 2 × 2. This can also be written as 24.
What is complete factorization?
complete factorization. one in which all polynomial factors (excluding monomial factors) are prime
for example, the factorization of 4x² + 8x – 60 to 4(x² + 2x – 15) is not complete because the trinomial x² + 2x – 15 can itself be factored.
