Intermediate Algebra — 5.4: Factoring Higher-Degree Polynomials

The same factoring techniques you learned for quadratics — GCF, difference of squares, trinomial factoring — extend directly to cubics and beyond. This lesson walks through three cubic equations step by step, showing how the degree of a polynomial predicts your maximum number of solutions and why factoring completely is essential to finding them all. Key concepts covered: • The six-step solving roadmap applied to degree-3 and higher polynomials • Degree-solution rule: a degree-n polynomial has up to n solutions • Extracting the complete GCF (not just part of it) before applying other techniques • Chaining GCF extraction into difference of squares: 7x³ − 63x = 0 • Recognizing when an equation is already partially factored (and why distributing is going backward) • The ac-method for trinomials with leading coefficient not equal to 1: 2y² − 13y + 15 • Why constant factors like the 3 in 3y never produce solutions • How incomplete factoring causes missed solutions (the lost ±3 problem) • Zero Product Property applied to three or more factors ━━━━━━━━━━━━━━━━━━━━━━━━ SOURCE MATERIALS The source materials for this video are from    • Intermediate Algebra Lecture 6.6:  Solving...
