First we use the equation gradient = (y1-y2)/(x1-x2) to find the gradient of the line L, using point A (-1,3) and point B (2,-3). This gives us gradient = (3-(-3)/(-1-2) = (3+3)/(-3) = -2. Now we subst...

So firstly, you want to split the equation into the format of a^2 + bx + c, so you know what a, b and c equal. a = 1b = -7c = 12 Now, you need to try to split the equation into the format (x + ?)(x + ?). ...

(a+b)² actually means (a+b)x(a+b) and so you have to solve this the long way unfortunately. You can use the grid method to do this [I would write this out on the whiteboard function at this poi...

When an object is solid, the particles have little energy and are closely packed together. When you heat an object, the particles gain energy and begin to move more frequently and randomly. This means tha...
