1. Draw sketch of line 2. Find gradient using m=(y₂ - y₁)/(x₂ - x₁)= 5--4/2--1=9-3=3 3. Choose one of the points and call it (a,b). I'll pick (2,5) because t...

Expanding and simplifying the right hand side: x²=4(x-3)(x-3)=4(x²-6x+9)=4x²-24x+36 Deducting 'x²' from both sides: 0=3x²-24x+36 Dividing by 3 and fa...

This is when the waves approach the coast at an angle result in the gradual zig-zag movement of beach materials along the coast.

The expression is of the form ax^2 + bx + c. Here, a = 1 and this makes it easier for us. We can also see that b = 5 and c = 6. In general, we have to find two numbers that multiply to get c and add to ge...

I would ask the tutee for the past paper that they were struggling with and talk through the reading passage with them, identifying key words to help answer the questions. French is more ambiguous with th...
