Answer:

Step-by-step explanation:
We have the quadratic equation
i.e. 
As, the roots of the quadratic equation
are given by
.
So, from the given equation, we have,
a = 1, b = -36 , c = -324.
Substituting the values in
, we get,

i.e. 
i.e. 
i.e. 
i.e.
and 
i.e.
and 
i.e. x = 43.45 and x = -7.45
Thus, the roots of the equation are 43.45 and -7.45.
Hence, the factored form of the given expression will be 
If i am not mistaken it is 4:12 but you can ask an expert to make sure
