ME AJUDEM

1- SENDO P (X) (2X^2-9X+2) ; Q(X) = (3X^2+7X-1) ; F (X) = (5X^3+5X^2-8) E K (X) = (2X^3+5X^2+4X). EFETUE O QUE SE PEDE:

A) F (X) + P (X) =

B) Q (X) + K (X) =

C) K (X) + F (X)

D) F (X) - K (X) =

E ) Q (X) - P (X) =

Answer 1

A. F (X) + P (X) =

5x³+5x²-8 + 2x²-9x+2 = 5x³+7x²-6

B. Q (X) + K (X) =

3x²+7x-1 + 2x³+5x²+4x = 5x³+5x²+11x-1

C. K (X) + F (X) =

2x³+5x²+4x + 5x³+5x²-8 = 7x³+10x²+4x-8

D. F (X) - K (X) =

5x³+5x²-8 - 2x³+5x²+4x = 3x³+4x-8

E. Q (X) - P (X) =


3x²+7x-1 - 2x²-9x+2 = x²+16x-3
