Find the zeros in (x+3)(x+1)=0

answer:

(x-3)(x-1)=0  

Two solutions were found :

x = 1

x = 3

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (x - 3) • (x - 1)  = 0  

Step  2  :

Theory - Roots of a product :

2.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation :

2.2      Solve  :    x-3 = 0  

Add  3  to both sides of the equation :  

                     x = 3

Solving a Single Variable Equation :

2.3      Solve  :    x-1 = 0  

Add  1  to both sides of the equation :  

                     x = 1

Two solutions were found :

x = 1

x = 3
