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.
