Question

find the value of a if x-a is factor of x²-ax²+a-1​

Answer 1

Answer:

a = 1/3

a = 0.3bar

Step-by-step explanation:

By using factor theorem in (x-a), we get,

x = a

p(x) = x^3 - ax^2 + 2x + a - 1 {given}

Now, putting the value of x = a, we get

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

a^3 - a^3 + 3a = 1

3a = 1

a = 1 ÷ 3

a = 0.3bar
