Question

A. Desarrollar cada binomio usando la regla general 1. (4m + 2n) 2. (2x + 5y) 3. (10x - 2y​

Answer 1

Explicación paso a paso:

Binomio al  cuadrado:

(a ± b)² = a² ± 2ab + b²

Binomio al cubo:  

(a ± b)³ = a³ ± 3a²b + 3ab² ± b³

Desarrollar cada binomio usando la regla general

1)

(4m+2n)² = (4m)²+2(4m)(2n)+(2n)²

(4m+2n)² = 16m²+16mn+4n²

2)

(2x+y)³ = (2x)³+3(2x)²(y)+3(2x)(y)²+(y)³

(2x+y)³ = 8x³+12x²y+6xy²+y³
