Q. A polynomial function h(x) with integer coefficients has a leading coefficient of 7 and a constant term of 2. According to the Rational Root Theorem, which of the following are possible roots of h(x)?Multi-select Choices:(A) −131(B) 718(C) −72(D) 41
Understand Rational Root Theorem: The Rational Root Theorem states that any rational root, expressed in its simplest form qp, must have p as a factor of the constant term and q as a factor of the leading coefficient.
Factor Constant Term: List the factors of the constant term 2: ±1, ±2.
Factor Leading Coefficient: List the factors of the leading coefficient 7: ±1, ±7.
Generate Possible Roots: Generate the possible rational roots by combining the factors of the constant term with the factors of the leading coefficient: ±11, ±71, ±12, ±72.
Simplify Roots List: Simplify the list of possible rational roots: ±1, ±71, ±2, ±72.
Compare with Given Choices: Compare the simplified list of possible roots with the given choices:(A) −131 is not a possible root because 13 is not a factor of the leading coefficient.(B) 718 is not a possible root because 18 is not a factor of the constant term.(C) −72 is a possible root because 2 is a factor of the constant term and 7 is a factor of the leading coefficient.(D) 41 is not a possible root because 4 is not a factor of the leading coefficient.
