  1. 1. Estado Libre Asociado de Puerto Rico Departamento de Educación Proyecto Cursos en Línea Identifica los polinomios según la cantidad terminos y grados El nombre: Fecha: I. Identifique cuales de las siguientes expresiones algebraicas son polinomios o no. 7. c2 + 2 – 3 =No 1. 2x3 = Sí c ___ 2. 7 - 3a2 = Sí 8. 3√n – 4 =_________________ 3. x3 + x-2 =_________________ 9. 2x (x2 + 3y) =_________________ 4. a2 + a =No 10. 3x – (2y + 4z) =_________________ a3 - 2 11. 6 + 2y =_________________ 5. 5x2 - 2xy + 3y2 =_________________ x 6. 6a + 3b =_________________ 12. 3 x + 2y =_________________ 4 II. Identifica cada polinomio de acuerdo a la cantidad de términos. 13. x2 + 10x + 5 = trinomio 16. 2m2n-mn2 =_________________ 14. 3a + 2b = binomio 17. 7a + b – 2 =_________________ 15. 4xyz = monomio 18. 6a2b2c2 =_________________ III. Indique el grado de cada polinomio. 19. 3x2 - x-2 + x – 3 = Grado 2 22. x + 2x2 + 3x3 + 6 =_________________ 2 6 4 20. x - x + x + 3 = Grado 6 23. 3x6 + 6x4 + x2– x =_________________ 21. 5x2y - 4x4y3 - 2 = Grado 7 (se suman los exponentes de cada término y se selecciona 24. 3x3y +2xyz – x4 =_________________ el que tenga mayor grado)
  2. 2. 25. 5x + yz =_________________ 28. x2 – 2xy + 3y3 =_________________ 26. x2y + xy2 =_________________ 29. 1 x2 + xy3 + y2 =_________________ 2 27. 6x2 + xy – y3 =_________________ 30. 4x3y2z – 3x2yz =_________________ IV. Realice las siguientes operaciones algebraicas, recuerde el orden de operaciones. 31. (3x2 + 1) + (x3 + x2 – 4)= Answer =_________________ 32. (4x 5 + 2x3 + x2 + 1) + (3x 4 + 6x3 + x2 – 2) Answer =_________________ 33. (2y3 – 8y2 + 3) + (2 + 4y + y2 – y3) Answer =_________________ 34. (3x4 – 4x3 – 5x + 12) + (x3 + 3x2 + 4x – 10) Answer =_________________ 35. (16x5y – 8x3y + 4x2y + 10x) + (15x44y + 3x3y + 5x2y- 5) Answer =_________________ 36. (10y2 – 8y + 9) – (3y2 + 4y + 3) Answer =_________________ 37. (18a3 – 12b2 – 3c) – (7a3 +13b2 –7c) Answer =_________________ 38. (16y3-10y2 + 13c– 6) – (-8 + 3y – 5 y2) Answer =_________________ 39. (13ab + 20ac – 15c) – (11ab –5ac –12c) Answer =_________________ 40. (14a2b2 + 24 a3b3 – 6a4b4) – (-6a4b4 + 8 a3b3 – 7 a2b2) Answer =_________________ 41. (2x2 – 3) (x2 + 4) Answer =_________________ 42. (a2 + ab + b2) (a – b) + (2a3 + b3) Answer =_________________ 43. (3x2 + 4) (2x2– 3) + 2x (3x – 5) Answer =_________________ 44. (x2 + 5x – 7) (x2 – x + 4) – (x + 2) (x –1) Answer =_________________ 45. (x2 – 2xy + 3y2) (3x + 2y) + 5x (x2 + 3xy) Answer =_________________ 46. 35x3z5 Answer =_________________ -7x2 y3z 47. πr2 h + 4πr2 Answer =_________________ πr 48. 18x2 y – 12 xy Answer =_________________ 3xy
