Algebra.Com's Answer #197397 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! The quadratic applies only to 2nd order equations. \n" ); document.write( "For cubics and quartics, look for info on google. \n" ); document.write( "They're a LOT more tedious. \n" ); document.write( "--------------- \n" ); document.write( "f(x) = \n" ); document.write( "For this one, the 32 is a clue. Look for roots that are powers of 2. \n" ); document.write( "2 is one. \n" ); document.write( "f(2) = 0 \n" ); document.write( "Then divide it by (x-2) and solve the quadratic. \n" ); document.write( " \n" ); document.write( " |
