Q. A polynomial function h(x) with integer coefficients has a leading coefficient of 2 and a constant term of −7. According to the Rational Root Theorem, which of the following are possible roots of h(x)?Multi-select Choices:(A) −1(B) −21(C) −7(D) 37
Rational Root Theorem: The Rational Root Theorem states that any rational root, in the form of qp (where p and q are integers and q=0), of a polynomial equation with integer coefficients is 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 −7: ±1, ±7.
Leading Coefficient Factors: List the factors of the leading coefficient 2: ±1, ±2.
Generate Possible Roots: Generate the possible rational roots by taking all combinations of the factors of the constant term over the factors of the leading coefficient: ±11, ±17, ±21, ±27.
Simplify Roots List: Simplify the list of possible rational roots: −1, 1, −7, 7, −21, 21, −27, 27.
Match with Choices: Match the simplified list of possible rational roots with the given choices: (A)−1,(B)−21,(C)−7,(D)37.
Identify Possible Roots: Identify which of the possible rational roots are in the given choices: −1 (A), −21 (B), −7 (C). The choice (D) 37 is not a possible root because 3 is not a factor of the leading coefficient 2.
