The following assignment is an elementary algebra level
assignment. The problems are given to illustrate how to use the site and get the
answers for the problems.


NOTE: The site does not give steps needed to solve the
problem. The student has to work this out, but the site provides the final
solution. This provides a quick check.


 The following examples are suggested to gain
familiarity with the site.


Student is encouraged to refer to his textbook to try
further examples. If some of the answers do not look familiar, please note that
advanced concepts will be learnt in higher level math courses.  



  • Algebra
    ? Expand


            
1.            
( 2 x + 3 ) ( x ? 3 )


 2.            
2x^2 * ( - 4 x ^3)


 



  • Algebra ? Factor expressions


 


1.            
4 x^2 ? 2 x


2.                 
x^2 ? 5 x + 6


3.                  
2 x^2 ? 3 x ? 9


4.                 
4 x ^ 2 ? 9 y ^ 2


 



  • Algebra
    - Simplify Expressions


 


1.     
        
3 x^2 + 6 y ^ 2 ? 4 x ^ 2 ? 5 y ^ 2


2.

  • Equations
    ? Simple Equations


 


1.< span style="font:7.0pt "Times New Roman"">                 
3 x + 5 ? 2 x ? 7 = 0


2.                 
3 y ? 7 ? 2 y + 8 = 4 y + 10


 



  • Equations
    ? Quadratic Equations


 


1.                 
x ^ 2 ? 9x + 14 = 0


2.                 
2 x ^2 ? 9 x ? 5 = 0


 



  • Graphs
    ? First and Second order


 


1.                 
y = - 4 x + 3


2.                 
y = x ^2 -  7 x + 12


3.                 
y = 2 x ^2 ? 8 x ? 10
