You can just plug in the different answers for x and see which one equals zero.
F(1) = 1 + 4 + 1 - 6 = 0
Answer:
C
Step-by-step explanation:
Note that if x = h is a root of a polynomial f(x) then f(h) = 0
Note the sum of the coefficients of the given polynomial
x³ + 4x² + x - 6 is
1 + 4 + 1 - 6 = 0
Hence x = 1 is a root( zero) and (x - 1) is a factor
