 Question 626927: Hi! I just want you to check if my answers are correct. Factor the expressions: 1. 15a^2(b-2)^2 + 20a^3(b-2)^3 = my answer is 5a^2(b-2)^2 [3 + 4a(b-2)] 2. 18p^2q^3 (r-6)+ 24(r-6) = my answer is 6(r-6)[3p^2q^3 + 4] 3. 24(x-y)^2 + 48(y-x) - 72(x-y)^3 = my answer is 24[(x-y)^2 + 2(y-x) - 3(x-y)^3] Lastly, -8.4x^3y^4 - 3.6x^2y^5 - 4.8x^4y^3.
