Question 738339: find two consecutive positive integers such that the square of the first decrease by 17 equals 4 times the second

consecutive positive integers: x, (x+1)
x^2 - 17 = 4(x + 1)
x^2 - 17 = 4x + 4
x^2 - 4x - 21 = 0
(x - 7)(x + 3) = 0
x = 7, x = -3
The integers are positive, so the integers are 7 and 8.
