Algebra.Com's Answer #787857 by Theo(13342)![]() ![]() You can put this solution on YOUR website! the two consecutive numbers are x and x + 1 \n" ); document.write( "therefore: \n" ); document.write( "x^2 + (x + 1)^2 = 41 \n" ); document.write( "simplify to get: \n" ); document.write( "x^2 + x^2 + 2x + 1 = 41 \n" ); document.write( "subtract 41 from both sides and combine like terms to get: \n" ); document.write( "2x^2 + 2x - 40 = 0 \n" ); document.write( "divide both sides of this equation by 2 to get: \n" ); document.write( "x^2 + x - 20 = 0 \n" ); document.write( "factor this quadratic equation to get: \n" ); document.write( "(x - 4) * (x + 5) = 0 \n" ); document.write( "solve for x to get: \n" ); document.write( "x = 4 or x = -5 \n" ); document.write( "since x is a natural number, than the only possible solution is x = 4 \n" ); document.write( "when x = 4, x + 1 = 5 \n" ); document.write( "your two natural numbers are 4 and 5. \n" ); document.write( "x^2 + (x + 1)^2 = 41 becomes: \n" ); document.write( "4^2 + 5^2 = 41 which becomes: \n" ); document.write( "16 + 25 = 41 which becomes: \n" ); document.write( "41 = 41, confirming the solution is correct. \n" ); document.write( "your solution is that the numbers are 4 and 5.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
