Verbetersleutel

  1. \(9p^{4}-30p^2s+25s^2=(3p^2-5s)^2\)
  2. \(121q^{4}-81x^2=(11q^2+9x)(11q^2-9x)\)
  3. \(9-64s^{8}=(3-8s^4)(3+8s^4)\)
  4. \(16b^{6}+24b^3q+9q^2=(4b^3+3q)^2\)
  5. \(100a^{4}-9b^2=(10a^2+3b)(10a^2-3b)\)
  6. \(100s^{6}-180s^3y+81y^2=(10s^3-9y)^2\)
  7. \(64p^{8}+176p^4+121=(8p^4+11)^2\)
  8. \(9x^{10}+30x^5+25=(3x^5+5)^2\)
  9. \(121-144p^{4}=(11-12p^2)(11+12p^2)\)
  10. \(144x^2+120x+25=(12x+5)^2\)
  11. \(9p^{6}+12p^3x+4x^2=(3p^3+2x)^2\)
  12. \(4s^2-p^{4}=(2s-p^2)(2s+p^2)\)
