Answer 2

4x^3 - 2x^2y = 2x^2 * 2x - 2x^2 * y

the answer is D

-24a^2b^3c^4 - 36a^4b^3c^2 = -6 ( 4a^2b^3c^4 + 6a^4b^3c^2) = -12 (2a^2b^3c^4 + 3a^4b^3c^2) = -12 * a^2 b^3 c^2 (2 * c^2 + a^2)

the answer is B

5xy^3 - 30x^3y + 15xy = 5(xy^3-6*x^3y+3*xy) = 5xy(y^2-6x^2+3)

the answer is D

Answer 3

4.D

5. B
