$\bg_white \fn_cs 7xy+2xz=x(7y+2z)$

ecuacion #2
$\bg_white \fn_cs 4xy-6xz+8xw =2x(2y-3z+4w)$

ecuacion#3
$\bg_white \fn_cs 5a^{5}b^{4}-10a^{3}b^{6}+20a^{2}b^{8}=5a^{2}b^{4}(a^{3}-2ab^{2}+4b^{4})$

ecuacion#4
$\bg_white \fn_cs x^{3}-9x^{2}+2x-18= x^{2}(x+4y)+y^{2}(x+4y)=(x^{2}+2)(x-9)$

ECUACION #5
$\bg_white \fn_cs x^{3}+4x^{2}y+xy^{2}+4y^{3}=x^{2}(x+4y)+y^{2}(x+4y)=(x^{2}+y^{2})(x+4y)$

ECUACION #6
$\bg_white \fn_cs 7x^{2}-14x-6x+12=7x(x-2)-6(x-2)=(7x-6)(x-2)$
