Find the value of a , if x-a is the factor of x^3-ax^2+2x+a-1

Answer»

Answer:

Given that x-a is a factor of x³-ax²+2x+a-1

So to get the VALUE of a we have

x-a=0 (BCZ of factor)

or x=a

Now x³-ax²+2x+a-1=0 For x=a

putting x=a we get

a³-a³+2a+a-1=0

or 3a=1

or a=(1/3)

If my answer satisfies you then GIVE me THANKS.
