Algebra.Com's Answer #1228 by khwang(438)![]() ![]() ![]() You can put this solution on YOUR website! At first you should know hwo to type \n" ); document.write( " A squared minus B squared minus 6B minus 9 as \n" ); document.write( " A^2 - B^2 -6B - 9\r \n" ); document.write( "\n" ); document.write( " You only need to use the basic formulas :\r \n" ); document.write( "\n" ); document.write( " A^2 - B^2 = (A-B)(A+B) ...(1) and \n" ); document.write( " (A+B)^2 = A^2 + 2 AB + B^2...(2)\r \n" ); document.write( "\n" ); document.write( " Now A^2 - B^2 -6B - 9 = A^2 - (B^2 +6B + 9) \n" ); document.write( " = A^2 - (B+3)^2 [Use formula (2), why?] \n" ); document.write( " = [(A+(B+3)][A-(B+3)] [Use formula (2)] \n" ); document.write( " = (A+B+3)(A-B-3)\r \n" ); document.write( "\n" ); document.write( " That is the whle story. \n" ); document.write( " Something if you suppose it is hard then it becomes more \n" ); document.write( " difficult.However,if youthink it is easy, it becomes facile. \n" ); document.write( " Math is not hard at all if you have basic confidence aboutyourself. \n" ); document.write( " \n" ); document.write( " Normally, don't anwser such simple questions as you asked. \n" ); document.write( " Here,I just don't want you see other long troublesome answers and \n" ); document.write( " I don't want you give up.\r \n" ); document.write( "\n" ); document.write( " Kenny \n" ); document.write( " |
