Answer:
=−6x^2y^8−8xy^6+12xy^3+2xy+4y−18
Explanation:
(−6x^2)(y^8)+12xy^3−6−xy^6+2y−6xy^6+2y−6−xy^6+2xy−6
=−6x^2y^8+12xy^3+−6+−xy^6+2y+−6xy^6+2y+−6+−xy^6+2xy+−6
Combine Like Terms:
=−6x^2y^8+12xy^3+−6+−xy^6+2y+−6xy^6+2y+−6+−xy^6+2xy+−6
=(−6x^2y^8)+(−xy^6+−6xy^6+−xy^6)+(12xy^3)+(2xy)+(2y+2y)+(−6+−6+−6)
=−6x^2y^8+−8xy^6+12xy^3+2xy+4y+−18
