Answer 1

Answer:

x + 2  is a factor

Step-by-step explanation:

f(x) = x³ + 3x²  + 5x  +  6

x + 2  is a factor  

if (f - 2) = 0

f(-2) = (-2)³ + 3(-2)² + 5(-2) + 6

=> f(-2) = -8 + 12 - 10 + 6

=> f(-2) = -18 + 18

=> f(-2) = 0

Hence x + 2  is a factor   of x³ + 3x²  + 5x  +  6

f(x) = 2x + 4

=> f(-2) = 2(-2) + 4

=> f(-2) = 0

=>  x + 2  is a factor   of 2x+ 4
