You can put this solution on YOUR website!
x^2 +16x + 4= 0
----
a = 1 ; b = 16 ; c = 4
----
Use the quadratic formula:
x = [-b +- sqrt(b^2-4ac)]/(2a)
------
x = [-16 +- sqrt(16^2 -4*1*4)]/2
------
x = [-16 +- sqrt(240)]/2
------
x = [ -16 +- 4sqrt(15)]/2
--------------------------------
x = -8+2sqrt(15) or x = -8-2sqrt(15)
