The complete exercise is: "<em>
If 
is a factor of 
, where b is a constant, what is the value of b?</em>
"</h3><h3 />
You know that a factor of the given polynomial is:
Then, in order to find the value of "b", which is a constant of the polynomial, you need to follow these steps:
1. You must rewrite the polynomial as:
2. Now you must substitute 
into the polynomial:
3. Since 2 is a zero of the polynomial, you can substitute 
:
4. Finally, you must solve for the constant "b" to find its value. Then, this is:
Answer:
{x,y}={

System of Linear Equations entered :
[1] x + 2y = 5
[2] x - y = 4
Graphic Representation of the Equations :
2y + x = 5 y + x = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = y + 4
// Plug this in for variable x in equation [1]
[1] (y +4) + 2y = 5
[1] 3y = 1
// Solve equation [1] for the variable y
[1] 3y = 1
[1] y = 1/3
// By now we know this much :
x = y+4
y = 1/3
// Use the y value to solve for x
x = (1/3)+4 = 13/3
Solution :
{x,y} = {13/3,1/3}
