Question
To what expression must $99 x^3-33 x^2-13 x-41$ be added to make the sum zero?
✓
Answer
In order to find the solution, we will subtract $99 x^3-33 x^2-13 x-41$ from 0 .
Required expression is
$0-\left(99 x^3-33 x^2-13 x-41\right)$
$=0-99 x^3+33 x^2+13 x+41$
$=-99 x^3+33 x^2+13 x+41$
So,
If we add $-99 x^3+33 x^2+13 x+41$ to $99 x^3-33 x^2-13 x-41$, then the sum is zero.
