Simplify 8a3−b33a2+10ab+8b2⋅2a2+5ab+2b24a2−b 2 completely.

8a3−b33a2+10ab+8b2⋅2a2+5ab+2b24a2−b2 
simplifying the expression we shall have:
8a^3+3b^3a^2+10ab+16b^2a^2+5ab+8b^2a^2-b^2
putting like terms together we get:
8a^3+3b^3a^2+(10ab+5ab)+(16b^2a^2+8b^2a^2)-b^2
=8a^3+3b^3a^2+15ab+24b^2a^2-b^2

 8a^3+3b^3a^2+15ab+24b^2a^2-b^2

Y=-2x-6 is the answer
