To solve this equation we have two different methods:
1) We can solve this method 'by hand' and is done by knowing how to factorise the quadratic and is done by looking at the equation gi...
This might be hard at first, but if you work through step by step you'll get there!
Start by getting rid of the fraction, multiply both sides by (3x-1) to get y(3x-1) = 2(1+x)
...
This question is about rearranging the equation so that we have all the unknown values on one side, and all the known values on the other side.To start, we want to put all the x values on one side, and al...
Here you need to use two formulae; one for the surface area of a sphere (4πr2) and one for the area of a circle (πr2).
First the surface area of the 6cm radius spher...
Here you need to use the quadratic formula, it cannot be solved by expanding out the brackets. In the formulae for which can be found on the formulae sheet. In this case a=5, b=8 and c=2.
