I got X=0 and X= -4. Case one: 0+2=2 2*2=4 4*2=8 8*2=16 Case two: -4+2= -2 -2*-2=4 4*-2= -8 -8*-2=16

X+2)^4=(+_2i)^4 ×=(+_ 2i-2)=2(+_1-1)

The real solutions are x=0 and x=-4. The complex solutions are x=-2+2i and x=-2-2i.

You're very much correct 👏

X = 0 is onequicksolution

(x+2)^4=16 (x+2)^4=2^4*e^(2*k*π*i) [(x+2)^4=2^4*e^(2*k*π*i)]^(1/4) x+2=2*e^(k*π*i/2) x=2*e^(k*π*i/2)-2 . . . k=0, ±1, ±, 2 ±3 x=2*(cos(k*π/2)+sin(k*π/2)*i)-2 k=0; x1=2-2=0 k=1; x2=2*i-2=-2*(1-i) k=2; x3=-2-2=-4 k=3; x4=-2*i-2=-2*(1+i)
