Anuja,

This equation $\displaystyle {x^3}-{4x^2}+x-2=0$ has complex roots

3. Hello,
this is a cubic equation. To solve it algebraically, you need to apply some (fairly complex) methods. Here is one : Cardano's Method.

4. This equation has actually one real root approximately 3.875 and two complex roots.
