Explicación paso a paso:
[tex]1.(2 + x) {}^{2} = (2) {}^{2} + 2(2)(x) + (x) {}^{2} = x {}^{2} + 4x + 4[/tex]
[tex]2.(3x - 5y) {}^{2} = (3x) {}^{2} - 2(3x)(5y) + (5y) {}^{2} = 9x {}^{2} - 30xy + 25y {}^{2} [/tex]
[tex]3. \: (x + y) {}^{2} = (x) {}^{2} + 2(x)(y) + (y) {}^{2} = x {}^{2} + 2xy + y {}^{2} [/tex]
[tex]4. \: (x - y) {}^{2} = (x) {}^{2} - 2(x)(y) + (y) {}^{2} = x {}^{2} - 2xy + y {}^{2} [/tex]
[tex]5. \: (2x + y) {}^{2} = (2x) {}^{2} + 2(2x)(y) + (y) {}^{2} = 4x {}^{2} + 4x + y {}^{2} [/tex]
[tex]6. \: (3x + y) {}^{2} = (3x) {}^{2} + 2(3x)(y) + (y) {}^{2} = 9x {}^{2} + 6xy + y {}^{2} [/tex]
[tex]7. \: (2x - 3y) {}^{2} = (2x) {}^{2} - 2(2x)(3y) + (3y) {}^{2} = 4x {}^{2} - 12xy + 9y{}^{2} [/tex]
[tex]8. \: (x + y) {}^{2} =esta \: es \: la \: misma \\ \: que \: la \: \\ tercera \: solo \: vuelvela \\ \: a \: copiar[/tex]
[tex]9. \: (x - 6) {}^{2} = (x) {}^{2} - 2(x)(6) + (6) {}^{2} = x {}^{2} - 12x + 36[/tex]
[tex]10. \: ( x + 9) {}^{2} = (x) {}^{2} + 2(x)(9) + (9) {}^{2} = x {}^{2} + 18x + 81 [/tex]
