Question

which of the following sets contains all the roots of a polynomial

F(x)=2x^3+x^2-3x

A- {0,1 3/2}

B- {-3/2, 1}

C- {-3/2, 0,1}

D- { -1, -3/2}

Answers

  1. The set that contains all the roots of the polynomial is given by:
    C. {-3/2, 0,1}

    What are the roots of a polynomial F(x)?

    They are the values of x for which F(x) = 0.
    In this problem, the polynomial is:
    F(x) = 2x³ + x² – 3x.
    Hence:
    2x³ + x² – 3x = 0.
    2x(x² + 0.5x – 1.5) = 0.
    2x = 0 -> x = 0.
    x² + 0.5x – 1.5 = 0 -> (x + 1.5)(x – 1) = 0.
    Then:
    • x + 1.5 = 0 -> x = -1.5.
    • x – 1 = 0 -> x = 1.
    Hence the correct option is:
    C. {-3/2, 0,1}
