Answer 2

Answer:

both are the factors ..............

step by step explanation :

x + 2

= x = -2

-2^3 + 3.-2^2 + 5.-2 + 6

-8 + 12 - 10 + 6

-18 + 18

0

x+2 is a factor of x^3 + 3x^2 + 5x + 6

2x + 4

x = -4/2

(-4/2)^3 + 3.(-4/2)^2 + 5.(-4/2 )+ 6

-64/ 8 + 48/4 - 20/2 + 6

-8 + 12 - 10 + 6

-18 + 18

0

2x + 4 is the factor of x^3 + 3x^2 + 5x + 6

hence , both are the factors of x^3 + 3x^2 + 5x + 6 .
