<PRE><B>Question 1085210</B>
The sum of a number and its square is 4 more than twice the number. Find the number. 
--------
Equation:
x + x^2 = 2x+4
------------------------
x^2 -x - 4 = 0
------
Quadratic formula::
x = [1 +-sqrt(1-4*-4)]/2
----
x = [1 +- sqrt(17)]/2
-----
x = (1/2)+(1/2)sqrt(17) or x = (1/2)-(1/2)sqrt(17)
------------
Cheers,
