    The roots of the equation 2m²+3=m are non-real roots.

    Step-by-step explanation:

    Given equation:

    2m²+3=m

    2m²-m+3=0

    Here, from the equation we can obtain the following values:

    a = 2, b = - 1, c = 3

    Discriminant of an equation is given as:

    D = b²-4ac

    = (-1) ²-4 (2) (3)

    = 1 - 21

    = - 20

    Discriminant can tell what kinds of roots the equation have.

    In our case, the discriminant is less than 0.

    When D < 0, the roots of the equation are complex conjugates. (non-real)
