    Given : x² + x + 5 = 0

    To find: The roots and Nature of the roots.

    Solution:

    x² + x +5 = 0

    Now we know , D = b² – 4ac

    so ,

    b = 1

    a = 1

    c = 5

    \therefore{D = b² - 4ac}

    D = (1 ) ² – 4 × 1 × 5

    D = 1 – 20

    D = -19

    As d is -19

    \therefore{D < 0}

    So, No real roots Exists.

    \therefore{The \:Roots \:Are \:Imaginary}

    The Nature of the roots are not real or imaginary.

    Step-by-step explanation:

    1. check D= b2-4ac
    2. if its negative then the roots are imaginary
    3. if its positive then roots are real
