v2.c17.s23.28

“The square of an optional number is multiplied by 8, decreased by unity, halved and then divided by that optional number. The quotient is one number. Half its square plus unity is the other number. Again, unity divided by twice an optional number added with that optional number is the first number and unity is the second number. The sum and difference of the squares of these two numbers minus unity will be (severally) squares.”¹
