‘Expand brackets and simplify’ are very common GCSE algebra questions
… and tend to be worth a few marks in most exam papers. The principles are fairly similar and, once you’ve decided on a method, it’s better to continue to practice that.
Bracketed terms are used frequently in maths, to describe solving quadratic or cubic functions, and can be useful in working with the different graphs. You’re actually creating the ‘original’ equation rather than taking the ‘original’ and then factorising.
Top Tips!
● These types of questions are very common at GCSE
● Crocodile, grid and FOIL are all common methods. They all work fine, although the grid can be a little tricky with higher level maths
● If you’re solving … you need to make sure that the equation is equal to zero. By ‘solving’ it means the values as the equation passes through the y = 0 line (axis)
● Be careful with multiplying negative numbers, two negatives make a positive :)
● Always work down the page and show your working methodically
