Question

Choose the correct sum of the polynomials (4x3 − 2x − 9) (2x3 5x 3). 6x3 − 3x − 6 2x3 − 7x − 12 6x3 3x − 6 2x3 3x − 3.

Answer 1

The correct sum of the polynomial is $\rm 6x^3 + 3x - 6$.

We have to determine

The correct sum of the polynomials.

Sum of the polynomials

Sum of the polynomials is just a matter of combining like terms, with some order of operations.

Then,

The correct sum of the polynomial is;

$\rm (4x^3 - 2x - 9) + (2x^3 + 5x + 3) \\\\ 4x^3 - 2x - 9 + 2x^3 + 5x + 3\\\\ 6x^3 + 3x - 6$

Hence, the correct sum of the polynomial is $\rm 6x^3 + 3x - 6$.
