smaller --- x
larger --- x+3
(x+3)^2 + x = 417
x^2 + 6x + 9 + x - 417 = 0
x^2 + 7x - 408 = 0
factor, then solve for x, reject the negative value for x
The difference between two positive integers is 3. If the smaller is added to the square of the larger, the sum is 417. Find the integers

let x = smaller , y = larger
y - x = 3 ... y - 3 = x
y^2 + x = 417
solve the system
y - x = 3 ... y - 3 = x
y^2 + x = 417
solve the system
