Answer:

4x^2+3x+y^2+30y+8

Step-by-step explanation:

given expression:

x^3+x(4x - x^2) + 3y^2 +12 - 4x^0 +2y(15 - y) + 3x

expand the terms we get:

x^3 + 4x^2 - x^3 + 3y^2 + 12 - 4 +30y - 2y^2 + 3x

bring all like terms together we get:

x^3 - x^3 + 4x^2 +3x + 3y^2 -2y^2 + 30y + 8

= 4x^2 + 3x + y^2 +30y + 8
