$\"P%28x%29++=+++x%5E3++-+47x%5E2+-+148x+-100\"$
\n" ); document.write( "to find the zeros, you must apply the \"rational root theorem\".
\n" ); document.write( "That is, use synthetic division to find zeros.
\n" ); document.write( "After doing the above, the factors are:
\n" ); document.write( "P(x) = (x+2)(x+1)(x-50)
\n" ); document.write( "x = {-2, -1, 50}
\n" ); document.write( "We can ignore the negative roots.
\n" ); document.write( "Find the number of frames that must be sold per month for the profit to be zero.
\n" ); document.write( "Profit will be zero when
\n" ); document.write( "50 frames are sold
\n" ); document.write( ".
\n" ); document.write( "For what x-values will the profit be positive?
\n" ); document.write( "x > 50
\n" ); document.write( " \n" ); document.write( "

\n" );
