Algebra.Com's Answer #522086 by DrBeeee(684)![]() ![]() ![]() You can put this solution on YOUR website! Let a = the smaller positive integer and \n" ); document.write( "let b = the larger positive integer \n" ); document.write( "Then we have two equations \n" ); document.write( "(1) b - a = 5 and \n" ); document.write( "(2) a + b^2 = 301 \n" ); document.write( "Solve (1) for b and substitute it into (2) and get \n" ); document.write( "(3) a + (5 + a)^2 = 301 or \n" ); document.write( "(4) a + 25 + 10a +a^2 - 301 = 0 or \n" ); document.write( "(5) a^2 + 11a - 276 = 0 \n" ); document.write( "Use the quadratic equation solution formul \n" ); document.write( "(6) \n" ); document.write( "(7) a = {-23,12} \n" ); document.write( "We select a = 12, because it must be a positive integer. Using (1) we get \n" ); document.write( "(8) b = 5 + 12 or \n" ); document.write( "(9) b = 17 \n" ); document.write( "Check these values using (2). \n" ); document.write( "Is (12 + 17^2 = 301)? \n" ); document.write( "Is (12 + 289 = 301)? \n" ); document.write( "Is (301 = 301)? Yes \n" ); document.write( "Answer: The two positive integers are 12 and 17. \n" ); document.write( "PS a = -23 and b = -18 should also be a solution. Try it in (2). \n" ); document.write( " |
