Algebra.Com's Answer #297936 by John10(297)![]() ![]() You can put this solution on YOUR website! Let x be the first ODD number then the next odd number is x + 2 \n" ); document.write( "The product is 63 \n" ); document.write( "x(x +2) = 63 \n" ); document.write( "x^2 + 2x - 63 = 0 \n" ); document.write( "(x + 9)(x - 7) =0 \n" ); document.write( "x = -9 OR x = 7 \n" ); document.write( "Since the question just needs the WHOLE number, so -9 is not the solution.\r \n" ); document.write( "\n" ); document.write( "Thus the first number is 7 and the next one is 7 + 2 =9\r \n" ); document.write( "\n" ); document.write( "Check: 7*9=63\r \n" ); document.write( "\n" ); document.write( "There you go! \n" ); document.write( " |
