    Y = 6x^2 + 10x - 4

    = 6x^2 + 12x - 2x - 4

    = 6x (x + 2) - 2 (x + 2)

    = (6x - 2) (x + 2)

    X intercepts are: - 2 and 1/3

    it is D

    X intercpe is when y=0

    0=6x^2+10x-4

    factor

    0=2 (3x^2+5x-2)

    assume

    0=3x^2+5x-2

    0 = (x+2) (3x-1)

    set to zero

    x+2=0

    x=-2

    3x-1=0

    x=1/3

    x intercepts are - 2 and 1/3

    D is answere
