This example demonstrates how to write a polynomial identity for factoring [math]x^2 + 3[/math] using GeoGebra. It involves core math concepts like polynomial identities and factoring. Key GeoGebra commands and objects used include GCD, Polygon, Line, Simplify, PrimeFactors, Unique, Length, Sequence, Product, If, and Textfield. Suitable for high school students learning polynomial transformations.

GeoGebra Commands & Parameters

  1. GCD(b, denom) → firstGCD
  2. Polygon((instructionEdge, y(Corner[1])), (instructionEdge, y(Corner[3])), Corner[4], Corner[1]) → instruction, instructionRight, instructionTop, instructionLeft, instructionBottom
  3. Line((x(Corner[1]) + ((2 * indent) * screenwidth), 0), yAxis) → align1
  4. Line((x(Corner[1]) + ((3 * indent) * screenwidth), 0), yAxis) → align2
  5. Line((x(Corner[1]) + ((4 * indent) * screenwidth), 0), yAxis) → align3
  6. Simplify((a * x^(2)) + (b * x) + c) → f
  7. PrimeFactors(absDiscriminant) → primeFactors
  8. Unique(primeFactors) → uniqueFactors
  9. Length(uniqueFactors) → numberFactors
  10. Sequence(CountIf[x ≟ Element[uniqueFactors, i], primeFactors], i, 1, numberFactors) → factorRepetitions
  11. Product(Sequence[Element[uniqueFactors, i]^(floor(Element[factorRepetitions, i] / 2)), i, 1, numberFactors]) → outsideroot
  12. If(discriminant < 0, "i", "") → imaginary_1
  13. GCD(outsideroot, denom) → secondGCD
  14. Textfield(a) → inputBox1
  15. Textfield(c) → inputBox3
  16. If(discriminant < 0, "+", "-") → signterm
  17. If(discriminant < 0, LaTeX["i^2"], "") → isquare

AI Drawing Prompt Reference

Draw a graph demonstrating polynomial factoring, showing how to factorize x^2 + 3. Include a horizontal axis, polygons on the right to represent the original polynomial, and text boxes on the left for the factoring steps and coefficients. Use lines for alignment. The order: draw the axis, construct polygons, label the factorization and coefficients, then align text boxes with lines.
