find two consecutive intgers such that the square of the sum of the two integers is 11 more than the smaller integer.
------------------------------------------
1st: x
2nd: x+1
----------------
Equation:
(x + x+1)^2 = x + 11
(2x+1)^2 = x + 11
4x^2 + 4x + 1 = x + 11
4x^2 + 3x - 10 = 0
4x^2 + 8x - 5x - 10 = 0
4x(x + 2) - 5(x + 2) = 0
(x+2)(4x-5) = 0
x = -2 or x = 5/4
