Answer:

Step-by-step explanation:x^6 + 63x^3 - 64 = 0? Factor it  

(x-1)(x+4)(x^2+x+1)(x^2-4x+16)  

x-1 = 0  

x = 1  

x+ 4 = 0  

x = -4  

Use the Quadratic Formula to slove  

x^2+x+1 = 0 False no sloution  

x^2-4x+16 = 0 False no sloution  

x = 1 or x =-4 are the solutions of the equation x^6 + 63x^3 - 64 = 0

Answer:

x^6+63x^3-64

x^6-x^3+64x^3-64

x^3(x^3-1)+64(x^3-1)

(x^3-1)(x^3+64)

{(x)^3-1)}{(x)^3+(4)^3}

(x-1)(x^2+x+1)(x+4)(x^2-4x+16)
