f(x)=x3-a2+x+2
f(a)=a3-a3+a+2
= a+2=0
=>a=-2
f(a)=a3-a3+a+2
= a+2=0
=>a=-2

Answer:
a = -2
Step-by-step explanation:
Given : (x – a) is a factor of
To Find : Find the value of A
Solution:
We are given that (x-a) is a factor
So, x-a = 0
x = a
So, a is the root of given equation
Since a is the root of equation
So, it must satisfy the equation.
Hence the value of a is -2
