Answer:
x = 3 , -1 +
, -1 - ![\sqrt{-1}](https://tex.z-dn.net/?f=%5Csqrt%7B-1%7D)
Step-by-step explanation:
⇒ ![p(x)=x^{3} -x^{2} -4x-6](https://tex.z-dn.net/?f=p%28x%29%3Dx%5E%7B3%7D%20-x%5E%7B2%7D%20-4x-6)
⇒ ![p(x)=(x-3)(x^{2} +2x+2)](https://tex.z-dn.net/?f=p%28x%29%3D%28x-3%29%28x%5E%7B2%7D%20%2B2x%2B2%29)
now, for zeros of
,
⇒ x =
± ![\frac{\sqrt{b^{2}-4ac } }{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7Bb%5E%7B2%7D-4ac%20%7D%20%7D%7B2a%7D)
⇒ x =
± ![\frac{\sqrt{2^{2}-4(2) } }{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B2%5E%7B2%7D-4%282%29%20%7D%20%7D%7B2%7D)
⇒ x = -1 ± ![\sqrt{-1}](https://tex.z-dn.net/?f=%5Csqrt%7B-1%7D)
hence, all the roots are,
x = 3, -1 +
, -1 - ![\sqrt{-1}](https://tex.z-dn.net/?f=%5Csqrt%7B-1%7D)
