Simplifying algebraic fractions

Cancel common factors

Sometimes needing to factorise equations to find common factors

1 of 6

Dividing polynomials

Use long division to divide the polynomial by one know factor in the form (x +/- a)

This allows you to find the other factor as of the expression and find its roots to draw a graph

2 of 6

Factor theorem

If f(x) is a polynomial

If f(a) = 0 then (x-a) is a factor of f(x)

3 of 6

Deduction

proving a statement is true starting from known facts

4 of 6

Exhaustion

Proving every option for a a statement is true

5 of 6

Counter example

Giving an example in which the statement is false
