Geometry The expression $$(1/3)({x}^{3}+5{x}^{2}+8x+4)$$ represents the volume of a square pyramid. The expression x + 1 represents the height of the pyramid. What expression represents the side length of the base? (Hint: The formula for the volume of a pyramid is V = (1/3)Bh.) How can polynomial division help you solve this problem?
