Hello,
\n" ); document.write( "First, let's add 14 to both sides.
\n" ); document.write( "x2-5x=14
\n" ); document.write( "Add 25/4 to both sides:
\n" ); document.write( "x2-5x+25/4=20 1/4
\n" ); document.write( "Factor this to:
\n" ); document.write( "(x-5/2)^2=20 1/4
\n" ); document.write( "Now square root both sides:
\n" ); document.write( "x-5/2=+-9/2
\n" ); document.write( "Add 5/2 to get:
\n" ); document.write( "x=7
\n" ); document.write( "x=-2
\n" ); document.write( "Make sense?
