X is a negative integer which is the largest
7x+4
x-4
5x
-5x

-5x

Step-by-step explanation:

Remember, if you multiply a negative number by a negative number, you will get a positive number, and positive numbers are greater than negative numbers. In this case, if I were to multiply each of these expressions with -1, I would get the following:

7(-1)+4=-3

-1-4=-5

5(-1)=-5

-5(-1)=5

And I'm sure you can imply how these values will correspond to other negative values. Basically, the last expression gives us a positive answer, which is larger than the others (which give a negative answer).

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
