Question

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

Answer 1

Respuesta:

$= - 3 {x}^{2} + x {}^{2} y - 2 {y}^{2} + 2y + 4x {y}^{2}$

Explicación paso a paso:

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

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

$4x {y}^{2} - 3 {x}^{2} - 2 {y}^{2} + 2y + {x}^{2} y =$

$= - 3 {x}^{2} + {x}^{2} y - 2 {y}^{2} + 2y + 4x {y}^{2}$
