Question

subtract:3x^2+4x^2y-5xy^2-y^2 from -5y^2+7x^2+4x^2y-7xy​

Answer 1

Step-by-step explanation:

$( - 5 {y}^{2} + 7 {x}^{2} + 4 {x}^{2} y - 7xy) - (3 {x}^{2} + 4 {x}^{2} y - 5x {y}^{2} - {y}^{2} ) \\ ⇒ - 5 {y}^{2} + 7 {x}^{2} + 4 {x}^{2} y - 7xy - 3 {x}^{2} - 4 {x}^{2}y + 5x {y}^{2} + {y}^{2} \\ ⇒ 4 {x}^{2} - 4 {y}^{2} + 5x {y}^{2} - 7xy .$
