document.write( "Question 396190: I did the following problem by synthetic division. Since this problem is rather llloooonnnngggg, I decided I need to have someone double check this. Could a tutor please look this over and tell me if I've done this correctly? I would greatly appreciate it! Thx! Here is the problem:\r
\n" );
document.write( "\n" );
document.write( "x^7+x^5-10x^3+12/ (x+2)\r
\n" );
document.write( "\n" );
document.write( "Since the divisor isn't in \"x-c\" form, I had to alter that. Also, lots of terms were missing in this problem, so I had to alter that, too. (That is what made this problem looonnnggg!) After I altered it, the problem looked like this:\r
\n" );
document.write( "\n" );
document.write( "x^7+0x^6+x^5+0x^4-10x^3+0x^2+0x+12 / (x-(-2))\r
\n" );
document.write( "\n" );
document.write( "My synthetic division went like this:\r
\n" );
document.write( "\n" );
document.write( "-2_| 1 0 1 0 -10 0 0 12
\n" );
document.write( " -2 4 -10 20 -20 40 -80
\n" );
document.write( "_____________________________________
\n" );
document.write( " 1 -2 5 -10 10 -20 40 -68 as remainder\r
\n" );
document.write( "\n" );
document.write( "So my answer is:\r
\n" );
document.write( "\n" );
document.write( "x^6-2x^5+5x^4-10x^3+10x^2-20x+40-68/(x-(-2))
\n" );
document.write( "
\n" );
document.write( " \r
\n" );
document.write( "\n" );
document.write( "YIKES!! Ok, is this correct, or do I need to go back to the drawing board with this? Any help would be welcomed!!! Thank you!! \n" );
