Answer 1

$3x-xy=x(3-y)\\\\6a-6b=6(a-b)\\\\12a-15b=3(4a-5b)\\\\8ax+8ay=8a(x+y)\\\\a^5+a^2=a^2(a^3+1)\\\\4b^2+8bc=4b(b+2c)\\\\12a^2b+28ab^2=4ab(3a+7b)\\\\-8xy-18y=-2y(4x+9)\\\\-3x^6+12x=3x(4-x^5)\\\\y^6+y^7=y^6(1+y)\\\\9x-27x^4=9x(1-3x^3)=9x(1-\sqrt[3]3x)(1+\sqrt[3]3x+\sqrt[3]9x^2)\\\\15a^2b-3ab=3ab(5a-1)$

$8x^4y^2-36x^3y^7=4x^3y^2\, (2x-9y^5)\\\\4a^2-8a^3+12a^4=4a^2\, (1-2a+3a^2)\\\\-15a^3b^2c-10a^2b^2c^2-5ab^2c^3=-5ab^2c\, (3a^2+2ac+c^2)$
