Question

Binomio al CUBO
5.-(X+3)3

Answer 1

(x + 3)³ = x³ + 9x² + 27x + 27

Explicación paso a paso:

Aplicar la fórmula del binomio al cubo: (a + b)³ = a³ + 3a²b + 3ab² + b³

• a = x
• b = 3

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

(x + 3)³ = x³ + 9x² + 3(x)(9) + 27

(x + 3)³ = x³ + 9x² + 27x + 27

Answer 2

Respuesta:

x^3 + 9x^2 + 27x + 27

Explicación paso a paso:

TEMA: BINOMIO AL CUBO

Fórmula

$(a + b) ^{3} = {a}^{3} + 3 {a}^{2}b + 3a {b}^{2} + {b}^{3}$

Resolver

$(x + 3) ^{3}$

${x}^{3} + 3( {x}^{2} )(3) + 3( x )( {3}^{2} ) + {3}^{3} \\ {x}^{3} + 9 {x}^{2} + 27x + 27$
