$\text{a, 6$x^{2}$ - 11x + 3}$
$\text{= 6$x^{2}$ - 2x - 9x + 3}$
$\text{= 2x(3x - 1) - 3(3x - 1)}$
$\text{= (2x - 3)(3x - 1)}$
$\text{b, 2$x^{2}$ + 3x - 27}$
$\text{= 2$x^{2}$ - 6x + 9x - 27}$
$\text{= 2x(x - 3) + 9(x - 3)}$
$\text{= (2x + 9)(x - 3)}$
$\text{c, 3$x^{2}$ - 5x - 2}$
$\text{= 3$x^{2}$ - 6x + x - 2}$
$\text{= 3x(x - 2) + (x - 2)}$
$\text{= (3x + 1)(x - 2)}$
$\text{d, 2$x^{2}$ - 5xy + 3$y^{2}$ }$
$\text{= 2$x^{2}$ + 6xy - xy + 3$y^{2}$ }$
$\text{= 2x(x + 3y) - y(x + 3y)}$
$\text{= (2x - y)(x + 3y)}$
$\text{Mik xin câu trả lời hay nhất ạ!}$
