    it's B.

    Step-by-step explanation:

    First solve f(x) = x^2 - 3x + 2 = 0

    Since (a + b + c = 0), use the Shortcut. The 2 real roots are x = 1 and x = c/a = 2.

    Use the algebraic method to solve f(x) > 0. Since a > 0, the parabola opens upward. Inside the interval (1, 2), f(x) is negative. Outside the interval (1, 2), f(x) is positive.

    answer by open intervals: (-infinity, 1) and (2, +infinity)

    graph{x^2 - 3x + 2 [-10, 10, -5, 5]}
