Answer :
Given:
[tex]\text{ The equation }x^3=-64[/tex]Required:
Solve the equation.
Explanation:
[tex]\begin{gathered} x^3=-64 \\ \text{ We can write it as} \\ x^3+64=0 \\ x^3+4^3=0 \\ \text{ We know }a^3+b^3=(a+b)(a^2+b^2-ab) \\ (x+4)(x^2+16-4x)=0 \\ x=-4,2-2\sqrt{3}i,2+2\sqrt{3}i \end{gathered}[/tex]Graphically
Answer:
Option B is correct.
