Question

efetue as seguintes adiçoes de polinomios:




a) (5ײ+5×-8) + (-2ײ+3×-2)

b) (3×-6y+4) + (4×+2y-2)

c) (5ײ-7×+2) + (2×2+7×-1)

d) (4×+3y+1) + (6×-2y-9)​

Answer 1

a) 3x^2 +5x -14
b) 7x -4y +2
c) 7x^2 +1
d) 4x -9y -8

Answer 2

Resposta:

a)3ײ + 8x -10

b)  -x -8y + 6

c)7x²+1

d)10x+y-8

Explicação passo-a-passo:

a)(5ײ+5×-8)+(-2ײ+3×-3)=

5ײ+5×-8-2ײ+3×-3=

5ײ-2ײ+5x+3x-8-3=

3ײ + 8x -10

b) (3x-6y+4)-(4x+2y-2)

3x - 6y + 4 - 4x - 2y + 2  

-x -8y + 6

c)5x²-7x+2+2x²+7x-1

(5x²+2x²)+(-7x+7x)+(2-1)

7x²+1

d)(4x + 3y+1)+(6x-2-9)

4x+3y+14+6x-2y-9

10x+y-8
