Enter the number of complex zeros for the polynomial function in the box.
f(x)=x4+5x2+6
x^4 + 5x^2 + 6 = 0 factor
(x^2 + 3) ( x^2 + 2) = 0
Settin each factor to 0 and solving for x we get that
x^2 + 3 = 0 x^2 + 2 =0
x^2 = -3 x^2 = -2
x = ±√-3 x = ±√ -2
x = ± i√ 3 x = ± i√ 2
So....4 complex roots (zeroes)
+4
