the sum of the squares of two consecutive odd positive integers is 130.
\n" ); document.write( " find the integers
\n" ); document.write( ":
\n" ); document.write( "Two consecutive odd integers, x and (x+2)
\n" ); document.write( ":
\n" ); document.write( "x^2 + (x+2)^2 = 130
\n" ); document.write( "FOIL (x+2)(x+2)
\n" ); document.write( "x^2 + x^2 + 4x + 4 = 130
\n" ); document.write( "Forms a quadratic equation
\n" ); document.write( "2x^2 + 4x + 4 - 130 = 0
\n" ); document.write( "2x^2 + 4x - 126 = 0
\n" ); document.write( "Factors to:
\n" ); document.write( "(2x + 18)(x - 7) = 0
\n" ); document.write( "The positive solution is all we want here
\n" ); document.write( "x = 7, 9 are the two consecutive odd positive integers
\n" ); document.write( ":
\n" ); document.write( "7^2 + 9^2 = 130
\n" ); document.write( "
