Question

when x minus A is a factor of x cube minus a x square + 2 X then the value of a is equal to​

Answer 1

Answer:

a = 0

Step-by-step explanation:

So,

x-a is factor of polynomial x^3-ax^2+2x

Zero of x-a =o

=> x = a

Let P(x) = x^3 -ax^2 +2x

So,

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

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

0 = 2a

0 = a
