Polynomials & Factoring

Control exponents, multiply cleanly, and recognize the factor patterns that make higher-degree algebra manageable.

Understand the idea

Direct answers and concept explanations that make the structure visible.

01Algebra · Concept explainerExponent rules that come from counting factorsThe rules are compressed descriptions of repeated multiplication. Knowing where they come from prevents powers from spreading across sums illegally.Algebra IConcept explainer
Work the method

Repeatable procedures with worked examples and checks.

02Algebra · Method guideMultiplying polynomials without losing a termEvery term in one factor multiplies every term in the other. Organize the products, then combine like terms once.Algebra IMethod guide03Algebra · Method guideFactor the greatest common factor before anything fancyThe GCF is the largest expression dividing every term. Removing it first exposes the smaller polynomial that actually needs attention.Algebra IMethod guide04Algebra · Method guideFactoring trinomials: use product and sum, not random guessingFor x² + bx + c, find two numbers with product c and sum b. For ax² + bx + c, split the middle term using product ac.Algebra IMethod guide06Algebra · Method guideCompleting the square without guessingAdd the exact term that turns a quadratic expression into a perfect-square trinomial, while preserving the equation's value.Algebra IIMethod guide
Choose a strategy

Comparisons for the moments when several methods look possible.

05Algebra · Decision guideDifference of squares or perfect-square trinomial?Recognize the pattern from term count, signs, square roots, and the middle coefficient—then expand to confirm rather than trusting appearance alone.Algebra IDecision guide
