Question

desarrolla los siguientes cuadradados de la suma de dos terminos 1 (4m+5n)² 2 (5x+3y)²

Answer 1

Respuesta:

(4m+5n)²: $16m^2+40mn+25n^2$

(5x+3y)²: $25x^2+30xy+9y^2$

Explicación paso a paso:

Para (4m+5n)²:

$(4m)^2+2(4m)5n+(5n)^2$

$16m^2+2(4m)5n+(5n)^2$

$16m^2+8m*5n+(5n)^2$

$16m^2+8m*5n+25n^2$

$16m^2+40mn+25n^2$

Para (5x+3y)²:

$(5x)^2+2(5x)3y+(3y)^2$

$25x^2+2(5x)3y+(3y)^2$

$25x^2+10x*3y+(3y)^2$

$25x^2+10x*3y+9y^2$

$25x^2+30xy+9y^2$
