I'm not sure how to solve quadratic systems. Here is an example of a problem:
\n" ); document.write( "(x-2)^2+y^2=5
\n" ); document.write( "x-y=1
\n" ); document.write( "---
\n" ); document.write( "Solve the linear equation for \"x\" and solve for \"y\":
\n" ); document.write( "---
\n" ); document.write( "x = y+1
\n" ); document.write( "-------------------
\n" ); document.write( "(y+1-2)^2 + y^2 = 5
\n" ); document.write( "----
\n" ); document.write( "(y-1)^2 + y^2 = 5
\n" ); document.write( "y^2 - 2y + 1 + y^2 = 5
\n" ); document.write( "2y^2 - 2y -4 = 0
\n" ); document.write( "2(y^2 - y -2) = 0
\n" ); document.write( "Factor:
\n" ); document.write( "2(y-2)(y+1) = 0
\n" ); document.write( "y = 2 or y = -1
\n" ); document.write( "------------------------
\n" ); document.write( "Solve for \"x\"
\n" ); document.write( "Since x = y+1, if y=2 then x = 3
\n" ); document.write( "Since x = y+1, if y = -1 then x = 0
\n" ); document.write( "----------------------------------------
\n" ); document.write( "Solutions:
\n" ); document.write( "(3,2) and (0,-1)
\n" ); document.write( "=======================
