SUMMARY

The cubic function x^3 + 2x^2 + x can be factored as x(x + 1)^2. This conclusion is derived from the Precalculus textbook by David Cohen, 3rd Edition, specifically in Chapter 1, Section 1.3, Question 44b. The factorization process involves recognizing common factors and applying the perfect square trinomial identity. Verifying the factorization by multiplying the factors back confirms its correctness.

PREREQUISITES
  • Understanding of polynomial functions
  • Familiarity with factoring techniques
  • Knowledge of perfect square trinomials
  • Basic algebraic manipulation skills

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.
