A fraction is simply a different way to write a division sum. I.e a \divide b = a/b.

This also applies if the two numbers we're dividing are fractions themselves:

a/b \divide c/d = (a/b) / (...

(x + 7)*(x - 7)

Notice difference of two squares. Very important to learn square numbers, primes and multiples and be able to notice them.

There are no shared members of either set. Sets A and B are mutually exclusive (odds and evens.) i.e. A intersect B has no members and is empty.

Using the equation of a straight line: y = mx + c (c is the y axis intercept, m is the gradient and y and x are points on the line (x,y))

e.g. if the gradient of the line was 3 and the line passes ...

The x-intercepts are where the graph crosses the x-axis
To find the x-intercepts of an equation --> substitute in y = 0 and solve for x

The y-intercepts are where the graph crosses the y-a...
