find the integral zero of 

4x^3=20x^2-X-5

The equation is 4x^3-20x^2-x+5
 

Integral Zero Theorem says that zeroes and roots of this polynomial,must be the factors of the constant term,this means the 

possible real roots of this polynomial are 1,-1,5,-5

Substituting values for P(x),we get

  • -1
