ayuda porfa ​

Answer 1

${(2 {x}^{2} + 3y )}^{2} = \\ {(2 {x}^{2} )}^{2} + {(3y)}^{2} + 2 \times 2 {x}^{2} \times 3y \\ 4 {x}^{4} + 9 {y}^{2} + 12 {x}^{2} y$

${(4 {x}^{2} - 5 {y}^{3} )}^{2} = \\ {(4 {x}^{2} )}^{2} + {(5 {y}^{3} )}^{2} - 2 \times 4 {x}^{2} \times 5 {y}^{3} = \\ 16 {x}^{4} + 25 {y}^{6} - 40 {x}^{2} {y}^{3}$

Explicación paso a paso:

${(x + y)}^{2} = {x}^{2} + {y}^{2} + 2xy$

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