There are a few ways to do this, firstly you notice that there is no coefficient in front of the x^2. This means you can factorise it with relative ease, by finding numbers that add to give 5 but multiply...

Differentiate y with respect to x:dy/dx = 2(x+3) = 2x+6When the above equation is equal to 0, this is where the turning point of the curve is.2x+6 = 02x = -6x = -3Therefore, at x = -3, the curve has a tur...

The aim is to finish with an equation that looks like "y = .....". We want Y and X on separate sides.The main thing to remember is that whatever you do to one side of the equation, you also do t...

So the first thing we would do is expand the right side: so multiply everything in the bracket by 2 to open it up -so it would become 2m - 14.3m + 5 > 2m -14Then we move all the like terms to one side ...

First let's start with the mean, the formula for the mean is: (Sum of terms)/(amount of terms). We know the amount of terms is 10 as this is in the questions, to find the sum of the terms we add all the m...
