This session is based on the material in section 2.4 of Kelley's "The Humongous Book of Calculus Problems"
The section presents a series of problems involving the solving of quadratic equations.
Problem 2.28
In[62]:=
 ![Solve[4x^2 + 4x15]](HTMLFiles/index_1.gif) 
Out[62]=
  
In[63]:=
 ![Solve[5x^23x - 6]](HTMLFiles/index_3.gif) 
Out[63]=
  
In[64]:=
 ![Solve[x^2 - 14x + 30]](HTMLFiles/index_5.gif) 
Out[64]=
  
In[65]:=
 ![Solve[4x^2 - 20x + 70]](HTMLFiles/index_7.gif) 
Out[65]=
  
These problems were all easily handled by Mathematica. But although it quickly gives the answer, there is no sense of how it arrived at the answer.
