$2\left(x^3+8x^2+16x\right)\left(x+4\right)$
Learn how to solve special products problems step by step online. Expand the expression (x^3+8x^216x)(x+4)+(x^3+8x^216x)(x+4). Combining like terms \left(x^3+8x^2+16x\right)\left(x+4\right) and \left(x^3+8x^2+16x\right)\left(x+4\right). Multiply the single term 2\left(x+4\right) by each term of the polynomial \left(x^3+8x^2+16x\right). Multiply the single term 2x^3 by each term of the polynomial \left(x+4\right). When multiplying exponents with same base you can add the exponents: 2x\cdot x^3.
