Find the value of a for which (x - 1) is a factor of the polynomial (a2x3 - 4ax + 4a - 1).

Answer :

If (x - 1) is a factor of the polynomial (a2x3 - 4ax + 4a - 1).

then it must satisfy it.


So, putting x = 1 the polynomial must be zero.


Putting x = 1 and equating to zero.


= (a2(1)3 - 4a(1) + 4a - 1)


= a2 - 4a + 4a - 1 = 0


= a2 = 1


So, a = �1.
