Question

Efetue as adições de polinômios:

a) (-2x+3y + ( 9x - 7y)

b) (6x^2 + 8x - 3) + (-2x^2 -5x - 1)

c) (-7 +2y - 6) + ( -3x - 4y - 5)

d) (x+1) + (3x^2 + 4x - 9)

Answer 1

a) -2x+3y+9y-7y= 7x-4y

b) 6x^2+8x-3 - 2x^2-5x-1= 4x^2+3x-4

c) -7+2y-6-3y-4y-5= -5y-13-5=-5y-18y

d) (x+1) + (3x^2+4x-9)= x+1+3x^2+4x-9= 3x^2+5x-8
