Answer 1

Resposta:

a) (2x²-9x+2)+(3x²+7x-1) _______ (R:5x² -2x + 1)

b) (5x²+5x-8)+(-2x²+3x-2) ______ (R:3x² + 8x - 10)

c) (3x-6y+4)+(4x+2y-2) ________ (R:7x -4y +2)

d) (5x²-7x+2)+(2x²+7x-1) _______ (R:7x²+ 1)

e) (4x+3y+1)+(6x-2y-9) _________ (R:10x +1y-8)

f) (2x³+5x²+4x)+(2x³-3x²+x) _____ (R:4x³ +2x²+ 5x)

g) (5x²-2ax+a²)+(-3x²+2ax-a²) ____ (R: 2x²)

h) (y²+3y-5)+(-3y+7-5y²) ________ (R: -4y² + 2)

i) (x²-5x+3)+(-4x²-2x) __________ (R:-3x² - 7x + 3)

j) (9x²-4x-3)+(3x²-10) __________ (R:12x² -4x- 13)
