If the zeroes are the result of whole numbers(X = 1,2,3,and etc),I eliminate
the trial and error portion by using
EXCEL spread sheets to find the zeroes; but in order to show your work, you will
probably have to use synthetic division.
Determine which consecutive integers the real zeros of the function are located.
f(x) = 4x^4 - 16x^3 - 25x^2 + 196x -146
Is there an easier way to this besides trial and error synthetic division?
Also, how do I approximate the real zeros?

You should double check your Eq, because the 2 zeroes that I found
were not the result of whole X values:
(-3.321 , 0.0) , (0.891 , 0.0).
I inputed values of X ranging from -10 to +10 and only found the two zeroes shown above. They would be almost
impossible to find by trial and error.
Good luck!
