    Its C.

    First get the equation into the form: Ax^2 + Bx + C = 0 (the quadratic equation)..

    We do this by subtracting 10x both sides (to get it on the other side)..

    9x^2 + 2 = 10x

    9x^2 – 10x + 2 = 10x – 10x

    9x^2 – 10x + 2 = 0

    Now the discriminant is: b^2 – 4ac

    The quadratic equation is Ax^2 + Bx + C = 0

    Here, A = 9, B = -10 and C = 2 so plug them in…

    (-10)^2 – 4 (9)(2)

    = 100 – 4 (18)

    = 100 – 72

    = 28 <— answer…

    So the discriminant is 28 (c).

  • lenpol7

    9x^2 – 10x + 2 = 0
    The discriminant is b^2 – 4ac
    Where
    a = 9
    b = -10
    c = 2
    Hence

    (-10)^2 – 4(9)(2) =
    100 – 72 =
    28

    First rewrite the equation as

    9x^2 – 10x + 2 = 0. Then the

    discriminant is (-10)^2 – 4*9*2 = 100 – 72 = 28

    – choice C
