    $3x^2 – 5xy + 2y^2 + 4x – 4y$
    $=3x^2 – 3xy – 2xy +2y^2 + 4x – 4y$

    $=3x(x-y) – 2y(x – y) + 4(x – y)$
    $=(x-y)(3x – 2y + 4).$

    Đáp án:

    $(x-y)(3x-2y+4)$

    Giải thích các bước giải:

    $3x^2-5xy+2y^2+4x-4y$

    $=3x^2-3xy-2xy+2y^2+4x-4y$

    $=3x(x-y)-2y(x-y)+4(x-y)$

    $=(x-y)(3x-2y+4)$
