This example generates random polynomials to help students understand the Factor Theorem. Key mathematical concepts include polynomials, the Factor Theorem, and its applications. It utilizes commands such as RandomPolynomial, Sequence, Expand, If, Coefficients, and Solutions in GeoGebra. Suitable for high school algebra and polynomial courses.

GeoGebra Commands & Parameters

  1. RandomPolynomial(2, -5, 5) → Q_{1}

  3. SelectedIndex(Level) → n
  4. Sequence(Random[1, 2], n, 1, 2) → a, {1, 2}
  5. Sequence(RandomElement[{1, 2, 3, 4, 5, -1, -2, -3, -4, -5}], n, 1, 2) → b, {2, 5}
  6. Expand((a(1) * x) + b(1)) → F
  7. If(a(1) ≟ a(2) ∧ b(1) ≟ b(2), Expand[F(x) + 1], Expand[(a(2) * x) + b(2)]) → D
  8. Expand((Q_{1}(x) * F(x))) → P_{1}
  9. Expand(((Q_{2}(x) * F(x)) * D(x))) → P_{2}

AI Drawing Prompt Reference

Create two random polynomials Q1 and Q2 with degrees 2 and 1, with coefficients chosen from −5 to 5. Randomly pick scalars a (either 1 or 2) and b from {2, 5}, and form a linear polynomial F from a·x + b. Then construct a second polynomial D by a conditional choice: if the sampled a and b pairs match, set D as F(x)+1; otherwise set D as a different linear expression with the other sampled coefficients. Next compute and expand P1 = Q1·F and P2 = Q2·F·D, include the solutions of D = 0, and also display G = D·F after expansion.
