shoe company closing down (algebra)

Question

a shoe company is going to close one of its two stores and combine all of the inventory from both stores. Store A can be represented by the polynomial A (x) = 15x^2 +3. Store B can be represented by the polynomial B(x) = -12x^2 - 2x. which expression represents the combined inventory of the two stores A(x) + B(x)?

Answer 1

A(x) = 15x^2 + 3

B(x) = -12x^2 -2

A(x)+B(x) = 3x^2 +1

Answer 2
