Rearranging formulae (AQA GCSE Maths): Flashcards

Single letter by itself on one side of equals sign

$P$

1. Substitute known values 2. Solve equation

Do the same operation to both sides

Use inverse operations to move other terms

Multiply both sides by the denominator

Expand the brackets first, then rearrange

Add the negative term to both sides to make positive

$p = \frac{N - 3q^2}{2}$

$h = \frac{2A}{b}$
