Learn how to solve special products problems step by step online. Expand the expression (x^2-4)(x^2+8)-(x^2+2)^2. Multiply the single term x^2+8 by each term of the polynomial \left(x^2-4\right). Multiply the single term x^2 by each term of the polynomial \left(x^2+8\right). When multiplying exponents with same base we can add the exponents. Multiply the single term -4 by each term of the polynomial \left(x^2+8\right).
