Answer:

y = -1

Step-by-step explanation:

Find roots (zeroes) of :       F(y) = y3-y2+2

Polynomial Roots Calculator is a set of methods aimed at finding values of  y  for which   F(y)=0  Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  y  which can be expressed as the quotient of two integersThe Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading CoefficientIn this case, the Leading Coefficient is  1  and the Trailing Constant is  2.
