Question

find the value of a,if x-a is a factor of x power 3-a power 2x+x+2.​

Answer 1

Answer:

If (x-a) is a factor of the given equation then a is a root of the equation. That is by substituting x=a in the above equation results 0.

(a^3)-a^2*a+a+2=0

a^3-a^3+a+2=0

a+2=0

a=-2

So there by value of a is -2
