You can put this solution on YOUR website!
4 + 9xy - 18y - 2x
\n" ); document.write( "Easier to see if you group it like this:
\n" ); document.write( "9xy - 18y - 2x + 4
\n" ); document.write( ";
\n" ); document.write( "Factor out 9y and you have
\n" ); document.write( "9y(x - 2) - 2x + 4
\n" ); document.write( ":
\n" ); document.write( "factor out -2
\n" ); document.write( "9y(x - 2) - 2(x - 2)
\n" ); document.write( ":
\n" ); document.write( "Factor out (x - 2) leaving:
\n" ); document.write( "(x - 2) (9y - 2)
\n" ); document.write( ":
\n" ); document.write( "Did this make sense to you? \n" ); document.write( "
