Hi, please note that if the degree of any polynomial is "n' then number of zeroes will also be 'n" for example any quadratic equation viz. ax^2+bx+c=0 is having two zeroes .. Similarly in ur question degree of this equation is 3. So I hope u got ur answer.

Also I would like to tell u one tip on how to find zero in short cut method called VEDIC Method : if the sum of all the coefficients of the variables is zero that means 1 is the factor of that equation. that means if x is the variable then x-1 will be the factor of the equation
