Question

Complete a tabela usando as regras fundamentais

Answer 1

Explicação passo-a-passo:

(1,2)=

x + y=1+2=3

2x - y = 2.1-2= 2-2=0

x²+y= 1²+2= 1+2= 3

(-2,1)=

x +y = -2 +1= - 1

2x -y = 2.(-2) - 1= - 4-1= - 5

x²+y = (-2)² + 1= 4+1= 5

( 2 , - 3)=

x + y = 2 -3= - 1

2x - y = 2.2 -(-3)= 4 +3= 7

x²+ y = 2² +(-3)= 4 -3= 1
