Hello,
\n" ); document.write( "Let's expand these out:
\n" ); document.write( " (3x+2)^2+(3x-2)^2=26
\n" ); document.write( "9x^2+12x+4+9x^2-12x+4=26
\n" ); document.write( "Combine like terms:
\n" ); document.write( "18x^2+8=26
\n" ); document.write( "Subtract 8 and divide by 18:
\n" ); document.write( "x^2=18/18 or 1
\n" ); document.write( "Sq rt both sides:
\n" ); document.write( "x=+-1
\n" ); document.write( "Make sense?
