Exercise
$r\left(r-1\right)\left(r-2\right)\left(r-3\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Solve the product r(r-1)(r-2)(r-3). Multiply the single term r\left(r-2\right)\left(r-3\right) by each term of the polynomial \left(r-1\right). When multiplying two powers that have the same base (r), you can add the exponents. Multiply the single term r^2\left(r-3\right) by each term of the polynomial \left(r-2\right). When multiplying exponents with same base you can add the exponents: r\cdot r^2\left(r-3\right).
Solve the product r(r-1)(r-2)(r-3)
Final answer to the exercise
$r^{4}-6r^{3}+11r^2-6r$
