Algebra.Com's Answer #310633 by pedjajov(51) ![]() 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( " \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( " \n" ); document.write( " \n" ); document.write( " |
