a)
the expressions for the two numbers.
a)

Answer to Problem 17E
Expressions for two numbers is (x−7) and (x+2) .
Explanation of Solution
Given information :
It is given that there are two integers. One is 7 less than a number, and the other is 2 greater than the same number.
Let the number be x.
According to the question,
First number = (x−7)
Second number = (x+2)
So,
Expressions for two numbers is (x−7) and (x+2) .
b)
the polynomial expression for the product of the numbers.
b)

Answer to Problem 17E
The expression after product of the numbers is x2−5x−14 .
Explanation of Solution
Given information :
It is given that there are two integers. One is 7 less than a number, and the other is 2 greater than the same number.
According to the question,
First number = (x−7)
Second number = (x+2)
So,
Polynomial expression for product of the numbers is (x−7)(x+2) .
After simplifying it,
(x−7)(x+2)=x2−7x+2x−14=x2−5x−14
So, the expression after product of the numbers is x2−5x−14 .
