A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x^2+12x+10) ft^3 and the volume of the water in the shallow end can be represented by (4x^2−100)ft^3. Write two different equivalent expressions ("simplified" and "simplified") that represent the total volume of the water in the pool in ft3.
