# An easy method to factorise an equation

hope this helps! it's just a bit easier than staring at the equation for about 10 minutes trying the find out the numbers! :)

First 92 words of the document:

Factorise the equation:

6y^2 + y 12 = 0

You need find two numbers that add to give one and times to give

72.

The 72 comes from multiplying the 6 and 12.

So we can work out that we can use 8 and 9.

So our equation becomes:

6y^2 8y + 9y 12 = 0

If we split this down the middle then we can create two different

brackets and then join them together, by factorising the equations

separately using only one bracket.

Notice how

these two brackets are the same.
