Solutions

Chapter 1.1, Problem 12E
To determine

To state: the property of real numbers used in the given relation.

Expert Solution

Answer to Problem 12E

Distributiveproperty over multiplication of real numbers.

Explanation of Solution

Given information:

A relation is given as

  (x+a)(x+b)=(x+a)x+(x+a)b

Calculation:

Distributiveproperty over multiplication of real numbers:

Suppose a, b, c, andd arefour real numbers, Distributive property over multiplicationsays that

  (a+b)(c+d)=(a+b)c+(a+b)d

Product of a number with a sum can be changed to sum of products.

Therefore, in (x+a)(x+b)=(x+a)x+(x+a)b , Distributive property over multiplication of real numbers has been used.
