Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression 7x^2y^3z^4(2x^8z-5x^3y^3-9x^5z^6). Multiply the single term 7x^2y^3z^4 by each term of the polynomial \left(2x^8z-5x^3y^3-9x^5z^6\right). When multiplying exponents with same base we can add the exponents. When multiplying exponents with same base you can add the exponents: 14x^{10}zy^3z^4. When multiplying two powers that have the same base (y^3), you can add the exponents.
