Can someone check my work

Question

I have to find the value of x^3 + 2x^2 - 3
My answer: 27 + 18 - 3

Answer 1

Your question the way it stands makes no sense, but it looks like
you are finding the value when x = 3

so the result is correct so far,
you just have to simplify it.

Answer 2

So my final answer would be: 42?
