Algebra.Com's Answer #826452 by greenestamps(13198)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "Notice that, in the formal algebraic solution from @boreal, you have to factor a quadratic expression by finding two numbers whose difference is 8 and whose product is 209. \n" ); document.write( "But that is exactly what the original problem asks you to do -- so that formal algebraic method doesn't help you get any closer to the answer. \n" ); document.write( "If you need a formal algebraic solution, use the nice \"trick\" shown by tutor @ikleyn. As she says in her response, it is a very useful method applicable to many problems. \n" ); document.write( "But if formal algebra is not required, clearly the fastest way to the answer is to find how the product 209 factors. \n" ); document.write( "209 = 11*19 \n" ); document.write( "So the two numbers are 11 and 19. \n" ); document.write( "Then, since the problem allows negative answers, another solution is -11 and -19. \n" ); document.write( " \n" ); document.write( " |
