You can put this solution on YOUR website!
Is your answer $\"-24x%5E5-10x\"$
\n" ); document.write( "If so, then no you're incorrect.
\n" ); document.write( "The degree of x in the solution should be lower than the degree of the original polynomial you started with like in the example,
\n" ); document.write( " $\"x%5E5%2Fx%5E2=x%5E3\"$
\n" ); document.write( "Use polynomial long division.
\n" ); document.write( "What do you need to multiply $\"%285x%2B3%29\"$ by to get $\"10x%5E3\"$ .
\n" ); document.write( "It would be $\"2x%5E2\"$ since $\"2x%5E2%285x%29=10x%5E3\"$ .
\n" ); document.write( "So $\"%282x%5E2%29\"$ multiplied by (5x+3) would yield $\"10x%5E3%2B6x%5E2\"$ .
\n" ); document.write( " $\"%2810x%5E3+-34x%5E2+-59x+-21%29-%2810x%5E3%2B6x%5E2%29=-40x%5E2-59x-21\"$
\n" ); document.write( "The next factor would be $\"-8x\"$ which yields $\"-40x%5E2-24x\"$ .
\n" ); document.write( "Subtracting then gives,
\n" ); document.write( " $\"%28-40x%5E2-59x-21%29-%28-40x%5E2-24x%29=-25x-21\"$ .
\n" ); document.write( "Finally, the next multiplier is $\"-5\"$ and $\"-5%285x%2B3%29=-25x-15\"$
\n" ); document.write( "Subtracting,
\n" ); document.write( " $\"-25x-21-%28-25x-15%29=-6\"$
\n" ); document.write( "So then putting it all together,
\n" ); document.write( " $\"%2810x%5E3+-34x%5E2+-59x+-21%29%2F%285x%2B3%29=2x%5E2-8x-5-6%2F%285x%2B3%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
