Question

determine (x+1) in a factor of x4+3x3+3x2
​

Answer 1

Answer:

if x + 1 is a factor then x = -1

Step-by-step explanation:

By substituting in x4+3x3 + 3x2

= (-1)^4 + 3(-1)^3 + 3(-1)2

= 4+ (-3) + 3

= 4 - 3 + 3

= 4

If x is a factor then p(x) should be zero but it is not equal to 0.So it is not a factor.
