Which of the following polynomials corresponds to the product of the multivariate polynomials 4x - 3y + 5 and x + 2y -3?
5x - y + 2
4x 2 - 6y 2 - 15
4x 2 + 8xy - 12x - 3y + 5
4x 2 - 6y 2 + 5xy - 7x + 19y - 15

Step-by-step explanation:

Let's solve the problem, but first remember the following:

when you are going to multiply two polynomials each of them involving several terms, then the multiplication is the sum of multiplying each term from the first polynomial by each of the terms of the second one.

In your practical exercise this means the following:

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
