How many complex roots does the polynomial equation have?3x5−2x+1=0

Answer : The given polynomial equation can have 0,2 or 4 complex roots.Explanation:-Given polynomial equation is [tex]3x^5-2x+1=0[/tex] which is a polynomial of degree 5.We know that the complex roots always occur in pair ,therefore the number of complex roots in any polynomial must be an even number but less than equal  to the degree of polynomial.Thus, the given polynomial equation has 4 complex roots.
