Answer:
The beam should be placed 8 feet from the center.
Step-by-step explanation:
The struts are y = √(x + 8) and y = √(x − 4).  The struts are 2 feet apart at the location of the beam:
√(x + 8) − √(x − 4) = 2
Solving:
√(x + 8) = 2 + √(x − 4)
x + 8 = 4 + 4√(x − 4) + x − 4
8 = 4√(x − 4)
2 = √(x − 4)
x − 4 = 4
x = 8

Answer:
Step-by-step explanation:
I think you are trying to use synthetic division for 
 divided by x-3
 divided by x-3 
First  
x -3 = 0 , make it equal to 0 and add 3 to both sides 
x = 3
Then we write all the coefficients and continue with 
a pattern of multiply by 3 and add to the next coefficient.
