<PRE><B>Question 320461</B>
My problem is writing a quadratic equation from the solutions: 3+4i, 3-4i. 
:
x = 3 +/- 4i
subtract 3 from both sides
x - 3 = +/- 4i
Square both sided
(x - 3)^2 = 16i^2
FOIL
x^2 - 3x - 3x + 9 = 16(-1)
:
x^2 - 6x + 9 = -16
:
x^2 - 6x + 9 + 16 = 0
:
x^2 - 6x + 25 = 0; is the equation</PRE>
