Use distributive property of multiplication
x (x^2 - 3x +12) + 2 (x^2 - 3x + 12)
x^3 - 3x^2 + 12x + 2x^2 - 6x + 24
Combine the similar terms
x^3 - (3x^2 + 2x^2) + (12x - 6x) + 24
Answer:
x^3 - x^2 + 6x + 24

expand (x+2)(x^2-3x+12)
= x^3 -3x^2 + 12x + 2x^2 - 6x + 24
= x^3 - x^2 + 6x + 24

If you want it to be expanded, then
(x+2)(x^2-3x+12)
= x^3-3x^2+12x+2x^2-6x+24
= x^3-x^2+6x+24 (Answer)

(x+2)(x^2 - 3x +12)
Expand
x^3 - 3x^2 + 12x + 2x^2 - 6x + 24
Then rearrange
x^3 - x^2 + 6x + 24

What do you want doing with it - this is just an expression...
Do you want it fully expanding? Solving for zero? etc...
Please ask question a little more specifically.
