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
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.
these two brackets are the same.
