The best way to solve a quadratic function is to put brackets into the equation. Start with an example Find x when y=0 for the function y=x * 2 + 5 x + 6 As y=0 make the whole equation= 0: x * 2 + 5 x + 6=0 ...

Ok so we need to get 'y' by itself on the left hand side of equal sign. We will first try to remove the denominator by multiplying 'x' by (3+4y). This gives (3+4y)x = 1 - 2y. We will then expand the brackets...

To find the highest common factor of 24 and 90 we do this in three steps: 1. Find the prime factorisation of the two numbers. This means rewrite each given number as a product of only prime numbers. The prim...

All quadratic equations take the general form: ax 2 +bx+c=0 The first step used to comlete the square is to divide the whole equation by the a term, in our case 2 : 1) x 2 +(7/2)x+3=0 We then move our c term...

First, you have to work out whether the side you need to find is the hypotenuse or not. The hypotenuse is the longest side of the triangle, opposite the right angle. For this question, you use Pythagoras' th...
