The thing that I think are difficult are arithmetic sequence, solve radical equations, solve quadratic equations.
In an arithmetic sequence, the difference between consecutive terms is constant. This constant value is called the common difference. The General Term of an Arithmetic Sequence is :tn = t1 + d( n – 1 )
how to solve radical equations.
Step:
1.Isolate the radical
2.Square both sides
3.Solve for X
4.Check for Extraneous roots by substituting.
how to solve quadratic equations
We can Factor the Quadratic
Or we can Complete the Square
Or we can use the special Quadratic Formula
