Question

Add the following polynomials :-
2x^2y^2-3xy+4,5+7xy-3x^2y^2 and 4x^2y^2+10xy​

Answer 1

Step-by-step explanation:

$(2x {}^{2} y {}^{2} - 3xy + 4) + (5 + 7xy - 3x {}^{2} y ^{2} ) + (4x {}^{2} y {}^{2} + 10xy) \\ (2x { }^{2} y {}^{2} - 3x {}^{2} y {}^{2} + 4x {}^{2} y {}^{2} ) + ( - 3xy + 7xy + 10xy) + (4 + 5) \\ 3x {}^{2} y {}^{2} + 14xy + 9$
