Q. A polynomial function f(x) with integer coefficients has a leading coefficient of 7 and a constant term of 5. According to the Rational Root Theorem, which of the following are possible roots of f(x)?Multi-select Choices:(A) −1710(B) −95(C) −8(D) −1
Theorem Explanation: 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 5: ±1, ±5.
Leading Coefficient Factors: List the factors of the leading coefficient 7: ±1, ±7.
Generate Possible Roots: Generate the possible rational roots by taking all combinations of factors of the constant term over factors of the leading coefficient: ±11, ±15, ±71, ±75.
Simplify Roots List: Simplify the list of possible rational roots: ±1, ±5, ±71, ±75.
Check Given Choices: Check which of the given choices match the possible rational roots: (A) −1710 is not a possible root because 17 is not a factor of 7. (B) −95 is not a possible root because 9 is not a factor of 7. (C) −8 is not a possible root because 8 is not a factor of 5. (D) −1 is a possible root because it is in the list of possible rational roots.
