Answer 1

Answer:

x = -1,3

Step-by-step explanation:

Given,

1 is the zero of given polynomial.

Thus, (x - 1) is divisible by given polynomial.

Long Division Method :

x - 1) x³   - 3x²  -  x   +   3 (x² - 2x - 3

      x³    - x²

     -------------------------------

                -2x²  - x  + 3

                - 2x² + 2x

          ---------------------------------

                               -3x + 3

                              -3x  +  3

                   -------------------------------

                                               0

Now,

p(x) = 0

⇒ x² - 2x - 3 = 0

⇒ x² - 3x + x - 3 = 0

⇒ x(x - 3) + (x - 3) = 0

⇒ (x - 3)(x + 1) = 0

⇒ x = -1,3

Hope it helps!
