We use the form ax^2+bx+cTo factorise we need to put the equation into 2 bracketsThese 2 brackets will be in the form (x+k)(x+j) where k and j are to be foundWe need to find a combination of k and j for w...

We should begin this question first by introducing the concept, adding clarity and showing the marker that you understand the issues at hand. This is then followed by stating your view, using a subjunctiv...

Let's label the equations x² + y² = 25 (1) y - x = 1 (2). We can use substitution to solve this simultaneous equation. Let's make y the subject of the equation (2) and we get y = x...

They are different techniques usually used in poetry. Enjambement is run-on lines, that is, lines that do not have punctuation at the end but flow on immediately to the next line. It links ideas together ...

Firstly, you need to get the equation to equal zero, so that you can use the quadratic formula to solve. Therefore you subtract 7 from both sides, meaning the equation becomes: 3x^2+7x-20=0. Recall the qu...
