3(x^2-2x-15)
\n" ); document.write( "We can factor this expression even further.
\n" ); document.write( "It would look like this: 3(x-5)(x+3), thus the given result was incomplete.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(3x-5)(5x-15)
\n" ); document.write( "We can factor (5x-15) even further into 5(x-3), thus this expression was also incomplete.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3(x-5)(x-3)
\n" ); document.write( "We can not factor this expression further, thus it is the correct answer to our problem.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(3x-15)(x-3)
\n" ); document.write( "We can factor 3 out of the first term, so it would look like this: 3(x-5)(x-3).
\n" ); document.write( "Therefore, this expression was also incomplete.\r
