It’s True.. you take the “extreme” variable from each proportion and cross multiply them before setting them equal to the product of the two “means” (which are just the other 2 numbers in the proportions).
If i am understanding the question correctly, x<10
Option C: (x+4) and (x-1) are the factors of the equation
Explanation:
Given that the equation is 
We need to determine the factors of the equation.
Splitting the middle term, we get,

Grouping the terms, we have,

Let us factor out the term (x+4), we have,

Thus, the factors of the equation are (x+4) and (x-1)
Hence, Option C is the correct answer.
