You can put this solution on YOUR website!
You divide one polynomial with the other one by dividing highest terms.\r
\n" ); document.write( "\n" ); document.write( "But first we have to write polynomials like they have terms with all exponents,\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%5E4-2x%2B1+=+x%5E4%2B0x%5E3%2B0x%5E2-2x%2B1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For example for these two at the beginning highest terms are x^4 in first and x in the second. Dividing these two gives us x^3.
\n" ); document.write( "Now we should multiply x^3 with (x-3).
\n" ); document.write( "We get x^4-2x^3. We subtract like terms to get 2x^3.
\n" ); document.write( "Now we drop down next term 0x^2 and we repeat previous until we get to the terms we can't make division anymore. What's left is a reminder\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here is how it looks for this problem:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x^4+0x^3+0x^2-2x+1 / x-2 = x^3+2x^2+4x+6
\n" ); document.write( "x^4-2x^3
\n" ); document.write( "--------
\n" ); document.write( " 2x^3+0x^2
\n" ); document.write( " 2x^3-4x^2
\n" ); document.write( " ----------
\n" ); document.write( " 4x^2-2x
\n" ); document.write( " 4x^2-8x
\n" ); document.write( " ---------
\n" ); document.write( " 6x+1
\n" ); document.write( " 6x-12
\n" ); document.write( " -------
\n" ); document.write( " +13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check:
\n" ); document.write( "\"%28x-2%29%28x%5E3%2B2x%5E2%2B4x%2B6%29+%2B13\"
\n" ); document.write( "\"x%5E4%2B2x%5E3%2B4x%5E2%2B10x-2x%5E3-4x%5E2-8x-12%2B13\"
\n" ); document.write( "\"x%5E4-2x%2B1\"
\n" ); document.write( "
\n" );
