Question

Please HELP me I need it :)

Answer 1

C

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

Answer 2

The answer is C. 1

You can just plug in the different answers for x and see which one equals zero.

F(1) = 1 + 4 + 1 - 6 = 0
