Answer: The required term to be added is
4x-12.

Step-by-step explanation: We are given the following product :


P=(x-3)(x+4).

We are to find the expression that must be added to (x² - 3x) to get the final answer.

To find the product, we need to multiply each term of the first expression (x - 3) to each factor of the second expression (x + 4).

We have


P\\\\=(x-3)(x+4)\\\\=x(x-3)+4(x-3)\\\\=x^2-3x+4x-12\\\\=x^2-3x+Q,

where


Q=4x-12.

Therefore, to get the final answer, we need to add the following expression :


Q=4x-12.

Thus, the required term to be added is
4x-12.
