Question

Calcule as somas algébricas: (x^2-3xy+y^2-x^2 y^2)-(-x^2-5x^2 y^2-3xy)= me ajudarrrr

Answer 1

Oie, Td Bom?!

$= (x {}^{2} - 3xy + y {}^{2} - x {}^{2} y {}^{2} ) - ( - x {}^{2} - 5x {}^{2} y {}^{2} - 3xy)$

$= x {}^{2} - 3xy + y {}^{2} - x {}^{2} y {}^{2} + x {}^{2} + 5x {}^{2} y {}^{2} + 3xy$

$= 2x {}^{2} + y {}^{2} + 4x {}^{2} y {}^{2}$
