Step-by-step explanation:

since x + 3 is a factor of the polynomial that means -3 is a value of x

substitute x = -3

next see attachment

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

(x) - (y) = (1 + 4i)
