Question

simply (a^3 b - xy^3)^2

​

Answer 1

Step-by-step explanation:

Use Identity: a^3 -b^3 = (a - b) ( a^2 +ab +b^2);

2^3(x+y) ^3 - (x-y) ^3= [(2x +2y -x+y)*(4(x+y)^2 +2(x^2-y^2) + (x-y)^2] =

(x + 3y)(4x^2 + 4y^2 +8xy + 2x^2 -2y^2 +x^2+y^2–2xy)=

(x+3y)(7x^2 +3y^2 +6xy); =>

A=7 ; B = 6; C =3;
