Question

add 2xy+7x²y² and -3x²y²+5xy​

Answer 1

Answer:

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

Answer 2

$\huge {\boxed{\orange { \boxed {\pink{\boxed{ \mathscr{ \blue {A{ \mathtt{ \green{N{ \mathbb{ \pink{S{ \bold{\purple{W{ \mathfrak{ \red{E}}}}}}}}}}}}}}{ \orange{\sf{R}}}}}}}}}$

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