Answer 1

Respuesta:

$(2x + 3y)^2 = 4x^2 + 9y^2\\\\(F)\\\\Comprobacion\\\\(2x)^2 + 2(2x)(3y) + (3y)^2\\\\4x^2 + 12xy + 9y^2$

$(2m - n)^2 = 4m^2 - n^2\\\\(F)\\\\Comproabcion\\\\(2m)^2 - 2(2m)(n) + (n)^2\\\\4m^2 - 4mn + n^2$

$(4m+3n)^2 = 4m^2 +24mn + 9n^2\\\\(V)\\\\Comprobacion\\\\(4m)^2 + 2(4m)(3n) + (3n)^2\\\\16m^2 + 24mn + 9n^2$

Answer 2

Respuesta:

1. F

2. F

3. V

Explicación paso a paso:

1. $(2x + 3y)^{2} =4x^{2} + 9y^{2}$

$(2x)^{2}$ + (2 · 2x · 3y) + $(3y)^{2}$

4$x^{2}$ + 12xy + 9$y^{2}$

2. $(2m-n)^{2}$ = $4m^{2} - n^{2}$

$(2m)^{2}$ - (2 · 2m · n) - $n^{2}$

4$m^{2}$ - 4mn - $n^{2}$

3. $(4m + 3n)^{2}$ = $4m^{2} + 24mn + 9n^{2}$

$(4m)^{2}$ + ( 2 · 4m · 3n) + $(3n)^{2}$

16$m^{2}$ + 24mn + 9$n^{2}$
