Quadratic simultaneous equations made super easy
Quadratic simultaneous equations made super easy

Just when you feel like you’ve got simultaneous equations sorted they throw in a quadratic into the mix.

Remember algebra makes up a huge part of GCSE Maths and so if you struggle with expanding, factorising etc. you really need to work on that.

Improving your algebra is one of the fastest ways to improve your grade.

The fast way to ‘Complete the Square’ that nobody tells you
The fast way to ‘Complete the Square’ that nobody tells you

Just made a quick video in case you are stuck on completing the square.

With completing the square, it looks and sounds scarier than it is.

What you are doing is rewriting a quadratic in a different form.

So in this example, we want to write x^2 + 4x + 5 in completed square form.

Expanding Double/Triple Brackets - get better with algebra
Expanding Double/Triple Brackets - get better with algebra

If you want any hope in passing your gcse maths exam and if you want a half decent grade, you need to master expanding brackets (and factorising, but we’ll do that in another post.)

Expanding two (or more) brackets is where you need to be super careful.

Minus numbers can really trip you up.

However if you do it step by step, its fairly straightforward.

Expanding Brackets: a quick way to improve your maths
Expanding Brackets: a quick way to improve your maths

Expanding brackets is the process of removing the brackets from something like this: 3(x + 2)

(Thinking about it like removing the shells from a pistachio nut, might help you remember).

To remove the brackets or expand the expression, you need to multiply.

You multiply the number or letter that’s on the outside of the bracket with everything inside the bracket, but 1 step at a time:

Direct Proportion: More Chocolate = More Happiness
Direct Proportion: More Chocolate = More Happiness

2 things are directly proportional if increasing one of them increases the other by the same amount or the same scale factor.

For example: When you buy fruit, increasing the weight of the fruit, increases the price.

To answer questions based on direct proportion, you usually work out the cost of one and then multiply up accordingly.
