plz answer i can't solve plz help me ​

Answer 1

Answer: $-x^{2} y^{2}+4x^{2} y+xy^{2}-4$

Step-by-step explanation:

$(5x^{2} y^{2}-3x^{2} y+5xy^{2}+7)-(6x^{2} y^{2}-7x^{2} y+4xy^{2}+11)$

=$(5x^{2} y^{2}-6x^{2} y^{2})+(-3x^{2} y+7x^{2} y)+(5xy^{2}-4xy^{2})+(7-11)$

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