Answer 1

Respuesta:

D) 2

Explicación paso a paso:

$x^2-12y^2+4xy\\=\left(x^2-2xy\right)+\left(6xy-12y^2\right)$

-----------------------------------

• $x^2-2xy$

$=xx-2xy\\=x\left(x-2y\right)$

• $6xy-12y^2$

$=6xy-12yy\\=6xy+2\cdot \:6yy\\=6y\left(x-2y\right)$

-----------------------------------

$=x\left(x-2y\right)+6y\left(x-2y\right)\\=\left(x-2y\right)\left(x+6y\right)$
