Integers involve with negative, so D isn't the correct answer the correct answer will be A.

Let's solve ~




It's factorized now ~ And if you want to find the zeros then equate the expression with 0.
And you will get ;

The "product" of two numbers means you multiply them.
So, you are multiplying (8-n), where n = "a number," by 7.
Then, when you decrease (subtract) this product by 5, you get 40.
So the whole thing looks like
7(8-n) - 5 = 40.
The answers to the question is A.
