Exercise
$\left(x^3+8x^2+11x-20\right).\left(3x+x^2-4\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression (x^3+8x^211x+-20)(3x+x^2+-4). Multiply the single term 3x+x^2-4 by each term of the polynomial \left(x^3+8x^2+11x-20\right). Multiply the single term x^3 by each term of the polynomial \left(3x+x^2-4\right). When multiplying exponents with same base we can add the exponents. When multiplying exponents with same base you can add the exponents: 3x\cdot x^3.
