Q. A polynomial function g(x) with integer coefficients has a leading coefficient of −7 and a constant term of −3. According to the Rational Root Theorem, which of the following are possible roots of g(x)?Multi-select Choices:(A) 1(B) 71(C) −3(D) 21
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 be such that p is a factor of the constant term and q is a factor of the leading coefficient.
Constant Term Factors: List the factors of the constant term −3: ±1, ±3.
Leading Coefficient Factors: 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, ±13, ±73.
Simplify Roots: Simplify the possible rational roots: ±1, ±71, ±3, ±73.
Match with Choices: Match the simplified possible roots with the given choices: (A)1,(B)71,(C)−3,(D)21.
Choice (A): Choice (A) 1 is a possible root because 1 is a factor of −3.
Choice (B): Choice (B) 71 is a possible root because 1 is a factor of −3 and 7 is a factor of −7.
Choice (C): Choice (C) −3 is a possible root because −3 is a factor of −3.
Choice (D): Choice (D) 21 is not a possible root because 2 is not a factor of −7.
