We can use synthetic division as a shortcut solution to this problem. The first is to put the root on the left side and the numeric coef. on the right side. Then down to 1 and multiply to the root. Add the numbers in the column.-10 | 1 0 -75 250 -10 100 -250 1 -10 25 0Since the final answer is 0, x + 10 is a factor of the function f (x) = x^3 - 75x + 250.
