Question

Qual o valor de ( x²-3xy+y²-x²y² ) - (-x²-5x²y²-y²-3xy) ?

Answer 1

Resposta:

2x^2 +2y^2 +4x^2 y^2

Explicação passo-a-passo:

(x^2 -3xy+y^2 -x^2 y^2) - (-x^2 -5x^2 y^2 -y^2- 3xy)

(x^2 -3xy+y^2 -x^2 y^2) - (-x^2 -5x^2 y^2 -y^2 -3xy)

x^2 -3xy+ y^2 -x^2 y^2-(-x^2 -5x^2 y^2- y^2 -3xy)

(x^2 -3xy+y^2 -x^2 y^2)-(-x^2 -5x^2 y^2- y^2- 3xy)

x^2 -3xy+y^2 -x^2 y^2 +x^2 +5x^2 y^2 +y^2 +3xy

x^2 +y^2 -x^2 y^2 +x^2 +5x^2 y^2 +y^2

x^2 -3xy +y^2 -x^2 y^2 +x^2 +5x^2 y^2 +y^2 +3xy

x^2 +x^2

x^2 +x^2

1x^2 +1x^2

(1+1)x^2

2x^2

x^2 -3xy +y^2- x^2 y^2 +x^2 +5x^2 y^2 +y^2 +3xy

2x^2 +y-x^2 y^2 +5x^2 y^2 +y^2

x^2- 3xy+y^2 -x^2 y^2 +x^2 +5x^2 y^2 +y^2 +3xy

(1+1)y^2

2y^2

x^2 -3xy+y^2 -x^2 y^2 +x^2 +5x^2 y^2 +y^2 +3xy

2x^2 +2y^2 -x^2 y^2 +5x^2 y^2

x^2 -3xy+y^2 -x^2 y^2 +x^2 +5x^2 y^2 +y^2 +3xy

-x^2 y^2 +5x^2 y^2

-1x^2 y^2 +5x^2 y^2

(-1+5)x^2 y^2

4x^2 y^2

x^2 -3xy+y^2 -x^2 y^2 +x^2 +5x^2 y^2 +y^2 +3xy

2x^2 +2y^2 +4x^2 y^2

Resposta

2x^2 +2y^2 +4x^2 y^2
