(x+100)^2+x^2=500^2
\n" ); document.write( "x^2+200x+10,000+x^2=250,000
\n" ); document.write( "2x^2+200x+10,000-250,000=0
\n" ); document.write( "2x^2+200x-240,000=0
\n" ); document.write( "2(x^2+100x-120,000)=0
\n" ); document.write( "2(x-300)(x+400)=0
\n" ); document.write( "x-300=0
\n" ); document.write( "x=300 is the width.
\n" ); document.write( "300+100=400 is the length.
\n" ); document.write( "Proof:
\n" ); document.write( "400^2+300^2=250,000
\n" ); document.write( "160,000+90,000=250,000
\n" ); document.write( "250,000=250,000
\n" ); document.write( "------------------------------------------
\n" ); document.write( "let x, x+2 & x+4 be the 3 integers.
\n" ); document.write( "(x+4)^2=(x+2)^2+264
\n" ); document.write( "x^2+8x+16=x^2+4x+4+264
\n" ); document.write( "8x-4x=264-16+4
\n" ); document.write( "4x=252
\n" ); document.write( "x=252/4
\n" ); document.write( "x=63 is the smallest integer.
\n" ); document.write( "61+2=65 for the middle integer.
\n" ); document.write( "61+4=67 is the largest integer.
\n" ); document.write( "Proof:
\n" ); document.write( "67^2=65^2+264
\n" ); document.write( "4,489=4,225+264
