What is the difference of the polynomials? (5x3 + 4x2) – (6x2 – 2x – 9) –x3 + 6x2 + 9 –x3 + 2x2 – 9 5x3 – 2x2 – 2x – 9 5x3 – 2x2 + 2x + 9

The difference of the polynomial is 5x^3-2x^2 + 2x +9

Explanation:

We have to find the difference

On distributing the minus over the parenthesis, we get

Now, we group the like terms and combine them

Therefore, the last expression is the correct option.

The difference of the polynomial is 5x^3-2x^2 + 2x +9
