1. factorising single brackets. example of factorising an algebraic expression: remember: 3x 6 is known as a binomial because it is an expression with two terms. 2. factorising double brackets. a) when factorising quadratic expressions in the form x 2 b x c. b) when factorising quadratic expressions in the form a x 2 b x c.

If an integer has only two factors, it is a prime number. for example, the factors of 5 are 1 and 5. step by step guide: prime numbers. if an integer has an odd number of factors, it is a square number. for example, the factors of 4 are 1, 2, and 4. this is because one factor is repeated. step by step guide: square numbers. Factorising into single brackets – 3 key steps. example: fully factorise the following: \textcolor{red}{12}\textcolor{limegreen}{x^2} \textcolor{red}{8}\textcolor{limegreen}{x} step 1 – take out the largest common factor of both the numbers, and place it in front of the brackets. Fully factorise: 1 find the highest c ommon factor (hcf) of the numbers 3 (the coefficient of x) and 6 (the constant). the highest common factor (hcf) of 3 x and 6 is 3. 2 write the highest common factor (hcf) at the front of the single bracket. 3 fill in each term in the bracket by multiplying out. 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. so if you were asked to factorise x² x, since.

Example. factorise \ (6x 9\). to factorise this expression, look for the hcf of \ (6x\)and 9 which is 3. to factorise, write down the hcf and then begin a set of brackets. find the missing terms. Examples, solutions, and videos to help gcse maths students learn how to factorise algebraic expression by taking out the highest common factor or greatest common factor. the following diagram shows how to factor the greatest common factor from a polynomial. scroll down the page for more examples and solutions of factoring the gcf. polynomial.
