Solution

Claro, aquí tienes el desarrollo paso a paso:

  1. Primero, distribuye cada término del primer paréntesis (x+4)(x + 4) a cada término del segundo paréntesis (3x1)(3x - 1):

(x+4)(3x1)=x(3x1)+4(3x1) (x + 4)(3x - 1) = x(3x - 1) + 4(3x - 1)

  1. Ahora, distribuye xx en el primer término:

x(3x1)=x3x+x(1)=3x2x x(3x - 1) = x \cdot 3x + x \cdot (-1) = 3x^2 - x

  1. Luego, distribuye 44 en el segundo término:

4(3x1)=43x+4(1)=12x4 4(3x - 1) = 4 \cdot 3x + 4 \cdot (-1) = 12x - 4

  1. Finalmente, suma los términos obtenidos:

3x2x+12x4 3x^2 - x + 12x - 4

  1. Combina los términos semejantes:

3x2+11x4 3x^2 + 11x - 4

Por lo tanto, la expresión (x+4)(3x1)(x + 4)(3x - 1) como un trinomio es:

3x2+11x4 3x^2 + 11x - 4
