Q. A polynomial function f(x) with integer coefficients has a leading coefficient of −5 and a constant term of 2. According to the Rational Root Theorem, which of the following are possible roots of f(x)?Multi-select Choices:(A) −51(B) 172(C) 2(D) 310
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 −5: ±1, ±5.
Generate Possible Rational Roots: Generate the possible rational roots by combining the factors of the constant term with the factors of the leading coefficient: ±11, ±51, ±12, ±52.
Simplify Roots List: Simplify the list of possible rational roots: −1, −51, 1, 51, −2, −52, 2, 52.
Check Given Options: Check the given options against the list of possible rational roots.(A) −51 is in the list, so it's a possible root.(B) 172 is not in the list because 17 is not a factor of the leading coefficient −5.(C) 2 is in the list, so it's a possible root.(D) 310 is not in the list because 3 is not a factor of the leading coefficient −5.
