Algebra.Com's Answer #351453 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! you're given one root and you need to find the other two (the equation is 3rd degree)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "-1 is a root, so x+1 is a factor\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "divide x^3 + 3x^2 - 13x -15 by x+1 and factor the result to find the two remaining roots \n" ); document.write( " |
