How do you Factorise expressions?

To factorise an expression fully, take out the highest common factor (HCF) of all the terms. For example, is the HCF of 4 x 2 and as 2 is the biggest number that will divide into 4 and 6 and is the biggest variable that will divide into and .

How do you Factorise steps?

A Method For Simple Cases

  1. Step 1: Find two numbers that multiply to give ac (in other words a times c), and add to give b.
  2. Step 2: Rewrite the middle with those numbers:
  3. Step 3: Factor the first two and last two terms separately:

How do you Factorise quadratics?

In order to factorise a quadratic algebraic expression in the form ax2 + bx + c into double brackets:

  1. Multiply the end numbers together ( a and c ) then write out the factor pairs of this new number in order.
  2. We need a pair of factors that + to give the middle number ( b ) and ✕ to give this new number.

How do you factor 4p with difference of perfect squares?

Here, “4” is a common factor and “p” is common too, so the first step is to take out “4p”: Now, recognise that inside the brackets we have a perfect square in the form a²-b². We now use the difference of perfect squares formula to factorise this further: These are expressions of the form ax² + bx + c.

How do you factor an expression with two terms?

There are two methods of factorising an expression with two terms. Look for something in common between the 2 terms. Often this will be an “x” or “a” bracket (x+a) The second method is where nothing is common. Usually, one term will be an ‘x²’ and the other term will be a number. This will be in the form a² – b².
