The remainder when x+3 divides x^4+7x^3-15x^2-8x+m is 23. find the value of m.
\n" ); document.write( ":
\n" ); document.write( "Use synthetic division:
\n" ); document.write( ":
\n" ); document.write( ".....____________________
\n" ); document.write( "-3|1 + 7 - 15 - 8 + m
\n" ); document.write( "..........-3 - 12 + 81 - 219
\n" ); document.write( ".....------------------------
\n" ); document.write( ".......1 + 4 - 27 + 73 + 23
\n" ); document.write( ":
\n" ); document.write( "Note we included the remainder, and m
\n" ); document.write( "We ask,\"What value of m, if 219 is subtracted, give us 23:
\n" ); document.write( "An equation for this statement would be:
\n" ); document.write( ":
\n" ); document.write( "-219 + m = 23
\n" ); document.write( "m = 23 + 219
\n" ); document.write( "m = 242
\n" ); document.write( ":
\n" ); document.write( "you can check this using normal long division
\n" ); document.write( ";
\n" ); document.write( "...........---------------------------------
\n" ); document.write( "(x+3)|x^4 + 7x^3 - 15x^2 + 8x + 242
\n" ); document.write( ";
\n" ); document.write( "See if you can do this. Let me know if you have difficulty with this. \n" ); document.write( "
\n" );
