I. Si:

P(x)= 7x - 4x + 1

Q(x)= 8x 14

N(x)= 5 17x + 8x

Calcular:

1. P(x) Q(x)2. N(x) P(x)3. Q(x) N(x)4. 3P(x) + 4Q(x)5. 2Q(x) 7N(x)6. -2N(x) 5P(x)7. P(x) + Q(x) + N(x)8. Q(x) + 4P(x) 8N(x)9. [-3P(x) + 2Q(x)] (Q(x) + N(x))

10. [-3 {2P(x) + 8N(x)} 7Q(x)] + P(x)II. Si:

P(x, y) = 12xy 25xy 13xy

Q(x, y) = -25xy - 14xy + 11xy

N(x, y) = 75yx 18xy - 11xy

Resolver:

11. E = 3P(x, y) 5Q(x, y)12. F = -11N(x, y) 2P(x, y)13. G = -5P(x, y) + 7Q(x, y) 11N(x, y)14. H = 4P(x, y) 15xy 7xy

15. I = 21xy + 15xy - 4N(x, y)16. J = 16xy - [7yx + P(x, y)]

17. K = 10xy [-yx + Q(x, y)]

18. L = -P(x, y) [N(x, y) + Q(x, y)]

III. Resolver:

19. Si el triple de Q(x), ms T(x) es igual al polinomio P(x). Hallar: T(x)Donde:

P(x) = 84x + 22x - 4

Q(x) = -23x + 11x + 6x + 13

20. Si N(x, y) es igual cudruplo del doble de S(x,y), menos M(x, y). Hallar: -5M(x, y)Donde:

N(x, y) = 4xy 15xy + 8

S(x, y) = -21xy + 17xy - 19

La perseverancia nos conduce hacia la meta.
