Question

show that (a+1) is not a factor of a³-2a²+3a+4.​

Answer 1

Answer:

Let us First assume that (a+1) is a factor.

This is done to verify that will be explained. If it is a factor then it must be equal to zero . Hence , a+1 is not a factor of . Hence proved

this is your answer pls mark

Answer 2

Answer:

please mark as brainiliest

Step-by-step explanation:

a=-1

a³-2a²+3a+4 =0

(1)^3-2(1)^2+3×1+4 =0

1-2+3+4 =0

6=0

LHS is not equal to RHS

hence proved
