Question

What should be added
2x ^3+ 3x^2+8x-4
to get 0 ? ​

Answer 1

-2x^3 - 3x^2 -8x + 4 should be added

Explanation:

Here, we want to know what should be added to the expression to get 0

What we should do in this case is to simply negate the values we have in the expression already

Adding the negated values will give 0

So, we have that;

-2x^3 - 3x^2 -8x + 4
