How do you Factorise double brackets in algebra?
In order to factorise a quadratic algebraic expression in the form ax2 + bx + c into double brackets:
- Multiply the end numbers together ( a and c ) then write out the factor pairs of this new number in order.
- We need a pair of factors that + to give the middle number ( b ) and ✕ to give this new number.
What does a double bracket mean in algebra?
Writing two brackets next to each other means the brackets need to be multiplied together. For example, ( y + 2 ) ( y + 3 ) means ( y + 2 ) × ( y + 3 ) . When expanding double brackets, every term in the first bracket has to be multiplied by every term in the second bracket.
How do you factor an equation with 2 terms?
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.
How do you Factorise algebra?
The simplest way of factorising is:
- Find the highest common factor of each of the terms in the expression.
- Write the highest common factor (HCF) in front of any brackets.
- Fill in each term in the brackets by multiplying out.
Can you use double parentheses?
2. Separate citations from parenthetical text with either semicolons (for parenthetical-style citations) or commas around the year (for narrative citations). Do not use a double enclosure or back-to-back parentheses.
What is an example of factorising single brackets?

What is factorising for GCSE Maths?
Here is everything you need to know about factorising for GCSE maths (Edexcel, AQA and OCR). You’ll learn the essentials of factorising expressions and factorising quadratics including factorising into single brackets and double brackets.
How do you find the factorization of a quadratic expression?
The original expression can be divided by 2 2 2 2, and then written as a product of two brackets. Divide each term by 2 2 2 2, and rewrite. To factorise the quadratic expression, we are looking for numbers that multiply to − 3 − 3 -3 − 3 and sum to − 2 − 2 -2 − 2.
