Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression 9b^2m(-3bm+4b^2m-7bm^2). Multiply the single term 9b^2m by each term of the polynomial \left(-3bm+4b^2m-7bm^2\right). When multiplying exponents with same base we can add the exponents. When multiplying exponents with same base you can add the exponents: -27bmb^2m. When multiplying two powers that have the same base (m), you can add the exponents.
Expand the expression 9b^2m(-3bm+4b^2m-7bm^2)
Final answer to the exercise
$-27b^{3}m^2+36b^{4}m^2-63b^{3}m^{3}$
