You can put this solution on YOUR website!
(4x+9)(15x^2-7x-2)=0
\n" ); document.write( "--------------
\n" ); document.write( "If the product is zero, then one of the factors must be zero. See that?
\n" ); document.write( "If (4x+9) = 0
\n" ); document.write( "4x = -9
\n" ); document.write( "x = -9/4
\n" ); document.write( "--------
\n" ); document.write( "If (15x^2-7x-2)=0
\n" ); document.write( "This is not as obvious, but you can factor it:
\n" ); document.write( "(5x+1)*(3x-2) = 0
\n" ); document.write( "Then either (5x+1) = 0 --> x = -1/5
\n" ); document.write( "----------
\n" ); document.write( "or (3x-2) = 0 --> x = 2/3
\n" ); document.write( "--------------
\n" ); document.write( "The 3 solutions are
\n" ); document.write( "x = -9/4
\n" ); document.write( "x = -1/5
\n" ); document.write( "x = 2/3
\n" ); document.write( " \n" ); document.write( "
\n" );
