    For part b, factorization will work. 9x^2 + 3x - 2 = 0 9x^2 + 6x - 3x - 2 = 0 3x(3x + 2) - 1(3x+2) = 0 (3x-1)(3x+2) = 0 x = 1/3, -2/3

    For A use this: Quadratic equation: \(ax^2+bx+c=0\) Discriminant of quadratic formula: \(b^2-4ac\) a = 3, b = -16, c = 2

    If \(b^2-4ac\) is positive → 2 real solutions 0 → 1 real solution negative → 0 real solutions
