To solve equation by factoring.
Answer to Problem 12PT
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 quadratic equation has real numbers, it will have roots.
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,
Calculation :
The above expression can also be written as.
In factored form.
Simplifying.
The above expression can be solved to get
We get only one root
