Question

find the value of a, if x-a is a factor of. x3 - ax2 + 2x + a - 1​

Answer 1

Step-by-step explanation:

x=a

now,x3-ax2+2x+a-1{given}

put the value of x which is a

a3-a(a)2+2a+a=1

a3-a3+3a=1

3a=1

a=1÷3

a=0.3bar

Answer 2

If x-a is factor of x3-ax2+2x+a-1,

then x-a=0 and x=a.

Put the value in equation and your answer will come a=1/3
