    D is correct option

    Step-by-step explanation:

    The correct option is D.

    The standard quadratic equation is ax²+bx+c=0

    Where a and b are coefficients and c is constant.

    It means that constant are on the L. H. S and there is 0 on the right hand side.

    Therefore to make it a quadratic equation first of all you have to add 11 at both sides so that the R. H. S becomes 0.

    The given equation is:

    2x2-x + 2 = - 11

    If we add 11 on both sides the equation will be:

    2x2-x + 2 + 11 = - 11+11

    2x^2-x+13=0

    Thus the correct option is D

    You can further solve it by applying quadratic formula ...
