Factorising

Factorization

In mathematics, factorization (also factorisation in British English) or factoring is the decomposition of an object (for example, a number, a polynomial, or a matrix) into a product of other objects, or factors, which when multiplied together give the original. For example, the number 15 factors into …

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. How do you Factorise an expression? To factorise an expression fully, take out the highest common factor (HCF) of all the terms.

Factorising is the reverse process of expanding brackets. To factorise an expression fully, means to put it in brackets by taking out the highest common factors. The simplest way of factorising is: Find the highest common factor of each of the terms in the expression.

What are the factors of an expression?

The factors in a mathematical expression are parts of the expression that are connected with multiplication. Lastly, the coefficients in a mathematical expression are the numbers that are multiplied by a variable. We use all of these different parts to create mathematical expressions.

What does factoring an expression mean?

Factoring (called "Factorising" in the UK) is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions.

What does it mean to factor an expression example?

factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

More Complicated Factoring

  • Factoring Can Be Hard !
    The examples have been simple so far, but factoring canbe very tricky. Because we have to figure what got multipliedto produce the expression we are given! It is like trying to find which ingredients went into a cake to make it so delicious. It can be hard to figure out!
  • Experience Helps
    With more experience factoring becomes easier. How can you learn to do that? By getting lots of practice, and knowing "Identities"!

6 hours ago Factorising. Factorising is the reverse of expanding brackets, so it is, for example, putting 2x² + x - 3 into the form (2x + 3) (x - 1). This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have.
