Click For Summary
To factor the cubic function x^3 + 2x^2 + x, the expression can be rewritten as x(x^2 + 2x + 1), which further factors to x(x + 1)(x + 1) or x(x + 1)^2. Verifying the correctness of the factorization can be done by multiplying the factors back together. Understanding how to factor is crucial for students, as it is a valuable mathematical skill. Mastery of factoring aids in solving more complex problems in precalculus and beyond.

Precalculus by David Cohen, 3rd Edition
Chapter 1, Section 1.3.
Question 44b.

Factor the expression.

x^3 + 2x^2 + x

x(x^2 + 2x + 1)

x(x + 1)(x + 1)

x(x + 1)^2

Correct?

yes . to check the corrcetness of the solution you can multiply it out and check
 
Factoring a very important. Students have no idea how valuable this skill is, honestly.
