D)7x²-8x+3-5x²+x+3

Preciso da conta me ajudem

Answer 1

Resolcendp a seguonte operacao :

A) 3p^2 + 17p^3 - 9p^3
=> 20p^3 - 9p^3
=> 11p^3

B) 8d - 5c - 13c + 9d + 3d^2
=> 8d + 9d - 5c - 13c + 3d^2
=> 17d - 18c + 3d^2

C) 7x^2y^2 + x^3 y - 6x^3y + x^2y^3
=> 7x^2y^2 - 5x^3y + x^2y^3

D) 7x^2 - 8x + 3 - 5x^2 + x + 3
=> 7x^2 - 5x^2 - 8x + x + 3 + 3
=> 2x^2 - 7x + 6
