Question

PLS ANSWER IT'S REALLY URGENT!

Determine the value of "a" if [x-a] is a factor of the polynomial x³-[a²-1] x+2.

Answer 1

Step-by-step explanation:

as x-a is a factor X= a

by substituting a

a^3 - (a^2- 1) a +2

a^3 - ( a^3 -a +2a^2-2)

a^3 - a^3 + a - 2a^2 + 2

-2a^2 + a + 2

by solving quadratic equation u can get value of a
