The factors of the given model are (x+2) and (x+7)
Given the representation of the model expressed as;
To get the factors, we will factorize the given quadratic function as shown:
Group the functions to have;
Factor out the GCF from both parenthesis:

The <em>correct answers</em> are:
A) Both can be solved by graphing;
C) Both can be solved by substitution; and
D) Both have solutions at the points of intersection.
Explanation:
Just as a system of linear equations can be solved by graphing, a system of quadratic equations can as well. We graph both equations. We then look for the intersection points of the graphs; these intersection points will be the solutions to the system.
We can also solve the system by substitution. If we can get one variable isolated, we can substitute this into the other equation to solve.
Answer:
A, the first option
Step-by-step explanation:
