64 plus 64 plus 64 is 192.
x3 + 4x2 + 16x + 64 =x2*(x + 4) + 16(x + 4) = (x + 4)*(x2 + 16) which has no further real factors.

64 is the cube of 4 so: x3 + 64 = (x + 4)(x2 - 4x + 16)
64 ÷ 4 + 11 =------------------(64 ÷ 4) + 11 =------------------16 + 11 =------------------= 27
x3 + 4x2 + 16x + 64 =x2*(x + 4) + 16(x + 4) = (x + 4)*(x2 + 16) which has no further real factors.
x2 + 12x - 64 = 0 ∴ (x + 16)(x - 4) = 0 ∴ x ∈ {4, -16}
The answer is 64. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
