Find three consecutive positive integers such that the sum of the squares of the first and second equals the square of the third.
\n" ); document.write( "-----------------------
\n" ); document.write( "1st: x-1
\n" ); document.write( "2nd: x
\n" ); document.write( "3rd: x+1
\n" ); document.write( "--------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "(x-1)^2 + x^2 = (x+1)^2
\n" ); document.write( "----
\n" ); document.write( "x^2-2x+1 + x^2 = x^2+2x+1
\n" ); document.write( "x^2 -4x = 0
\n" ); document.write( "x(x-4) = 0
\n" ); document.write( "---
\n" ); document.write( "Positive solution:
\n" ); document.write( "Let x = 4
\n" ); document.write( "1st: x-1 = 3
\n" ); document.write( "2nd: x = 4
\n" ); document.write( "3rd: x+1 = 5
