To solve equation by factoring.
Answer to Problem 13PT
Explanation of Solution
Given information :
The function provided is
Formula used :
For some of the equations the solution can be found by factoring. If the factored form of a
In the factored form it is assumed that at least one of the factors is equal to 0. Therefore, if product if two factors is 0 then at least one of the factors must be zero, this is known as the Zero Product Property
Either,
Or,
