I can't quite remember how to approach this one, I have three others, but I think I could solve them if someone helped walked me
through this one to jog my memory.
Solve the quadratic equation by completing the square.
x^2-10x+12=0
First, choose the appropriate form and fill in the blanks with the correct numbers.
Then, solve the equation.
(x+[])^2=[]
(x-[])^2=[]
If there is more than one solution, separate them with commas.
Solution:
x = []

First, note that 
is always positive (except for x=0), so 
must be always negative.
Thus, the only plausible graphs are 1 and 3 since they are below the x-axis.
Now, and are only defined for x≥0, because only for these x'es we can take the square root.
Note that the third graph has domain (-infinity, 0], so it is not the right one, while 1 is ok.
Answer: first graph
