To solve the given equation by factoring.
Answer to Problem 22MCQ
The value of x is -7 .
Explanation of Solution
Given information :
The equation provided is
Formula used :
The given equation can be solved by factoring. To do so, break up the midpoint to arrive at two factors. Then use the zero-product property to equate each factor in order to get the roots.
Calculation :
Given equation.
Breaking the middle term.
Arranging the common factors.
The two factors of the function.
Now, the root is:
Using zero-product property.
This is the value of x . Since both the factors are same, there is only one value of the equation.
