Download - WolframAlpha Examples part 3
The examples here show you how to use WolframAlpha for checking your work and exploring other examples.
For some topics other calculators and applets are also suggested to help you further.

Factorising Quadratic Expressions
Completing the Square
Note, we see that the minimum value of this function is 1 which happens when x= -3.
You should be able to see why this is the case from the completed square form.
See next slide also.

Solving Quadratic Equations
Note that if you choose ‘Show steps’ Wolfram Alpha will show the method for completing the square, but it is perhaps easier to solve this equation by factorising or using the quadratic formula.
