Q. A polynomial function h(x) with integer coefficients has a leading coefficient of 16 and a constant term of −1. According to the Rational Root Theorem, which of the following are possible roots of h(x)?Multi-select Choices:(A) 518(B) −18(C) 7(D) 1
The Rational Root Theorem: The Rational Root Theorem states that any rational root, in the form of qp (where p and q are integers), of a polynomial equation with integer coefficients must have p as a factor of the constant term and q as a factor of the leading coefficient.
Constant Term Factors: List the factors of the constant term −1, which are ±1.
Leading Coefficient Factors: List the factors of the leading coefficient 16, which are ±1, ±2, ±4, ±8, and ±16.
Possible Rational Roots: According to the Rational Root Theorem, the possible rational roots are the factors of the constant term divided by the factors of the leading coefficient. So, the possible roots are ±11, ±21, ±41, ±81, and ±161.
Check Given Options: Check each of the given options against the possible roots:(A) 518 is not a possible root because 5 is not a factor of 16.(B) −18 is not a possible root because 18 is not a factor of −1.(C) 7 is not a possible root because 7 is not a factor of −1.(D) 1 is a possible root because it is 50, and both 1 and 1 are factors of −1 and 16, respectively.
