(-4t-4v)(-5t-5v)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(-4t)*(-5t) + (-4t)*(-5v) + (-4v)*(-5t) + (-4v)*(-5v)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "20t^2 + 20vt + 20vt + 20v^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "20t^2 + 40vt + 20v^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So (-4t-4v)(-5t-5v) expands and simplifies to 20t^2 + 40vt + 20v^2\r
