Algebra.Com's Answer #248396 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Well, by looking at it, I can see that x = -1 is a root, so (x+1) is a factor... \n" ); document.write( "If you divide it by x+1 you get, \n" ); document.write( "2x^2 - 2x - 3 \n" ); document.write( "wich isn't directly factorable...you'd use the quadratic here... \n" ); document.write( "so that x = \n" ); document.write( "and the answer factored appears to be \n" ); document.write( "(x + 1)(x + (1+sqrt(7)/2)(x - (1+sqrt(7)/2) \n" ); document.write( " |
