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