Weegy: The correct answer is B. 3.
User: What are the real or imaginary solutions of the polynomials
x4 -54x2 + 576 = 0
A.
no solution
B.
-4, -6
C.
0,4,6
D.
-4,4,-6,6
(More) 8
x^2 + 2x + 2 = 0,
a = 1, b = 2, c = 2
b^2 - 4ac = 2^2 - 4(1)(2) = 4 - 8 = -4 < 0
therefore, there is no real solutions of the equation x^2 + 2x + 2 = 0.

x^4 -54x^2 + 576 = 0
(x^2 - 16)(x^2 - 36) = 0
(x + 4)(x - 4)(x + 6)(x - 6) = 0
x = -4, 4, -6, or x = 6
