a.
To Write: The procedure of how to solve the system by algebraically and graphically.
In algebraic method, quadratic formula of factorization method has been used.
In graphical method, locate the intersection of the equations to solve the system.
Given:
Explanation:
Solve
Algebraic method:
It has been clear that both equations are solved for
Set both the
Then the
After that by using quadratic formula or by factor method, the equation can be solved.
Graphical method:
First create a graph to locate the intersection of the equations. The intersection of
the system of equations is the solution.
b.
To Solve: The system in part
The solutions are
Given:
Explanation:
Solve
Algebraic method:
Set both the expressions equal to each other:
Rewrite the expression:
Factor the expression:
Substitute
Substitute
Hence the solutions of the system are
Graphical method:
First create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution.
Enter the functions
Point of intersections are
