\n" ); document.write( ":
\n" ); document.write( "4x^2 - 32x - 5x^2 + 35x + 4 = 0
\n" ); document.write( "Combine like terms
\n" ); document.write( "4x^2 - 5x^2 - 32x + 35x + 4 = 0
\n" ); document.write( "-1x^2 + 3x + 4 = 0
\n" ); document.write( "Multiply by -1
\n" ); document.write( "x^2 - 3x - 4 = 0
\n" ); document.write( "Factors to
