Algebra.Com's Answer #549939 by Theo(13342)![]() ![]() You can put this solution on YOUR website! as far as i can see, none of them are equal.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "A is the set {1,2,3} \n" ); document.write( "there are 3 elements in the set. \n" ); document.write( "those elements are x = 1, x = 2, x = 3.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "B is solved for as follows: \n" ); document.write( "x^2 - 2x + 1 = 0 \n" ); document.write( "factor this to get (x-1)^2 = 0 \n" ); document.write( "that gets you x = 1 as the only value of x in the set.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "C is solved for as follows: \n" ); document.write( "start with x^3 - 6x^2 + 11x - 6 = 0 \n" ); document.write( "your rational roots, if any, will be a combination of the factors of the coefficient of x^3 multiplied by the factors of the constant term. \n" ); document.write( "that would make the possible roots as plus or minus {6,3,2,1) \n" ); document.write( "you can use synthetic division to eliminate these possibilities. \n" ); document.write( "6 is not a root, but 1, 2, and 3 are all roots.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "selections A and C are equivalent.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "if you need help on how to perform synthetic division, here's a reference.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "http://www.wtamu.edu/academic/anns/mps/math/mathlab/col_algebra/col_alg_tut37_syndiv.htm\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "if you need help on how to determine the rational roots of an equation, here's a reference that can help.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "http://www.wtamu.edu/academic/anns/mps/math/mathlab/col_algebra/col_alg_tut38_zero1.htm\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
