Solution

Claro, aquí tienes la solución paso a paso:

  1. Distribuir cada término del primer paréntesis por cada término del segundo paréntesis:

    (2x+3)(3x1)=2x3x+2x(1)+33x+3(1) (2x + 3)(3x - 1) = 2x \cdot 3x + 2x \cdot (-1) + 3 \cdot 3x + 3 \cdot (-1)

  2. Realizar las multiplicaciones:

    2x3x=6x2 2x \cdot 3x = 6x^2 2x(1)=2x 2x \cdot (-1) = -2x 33x=9x 3 \cdot 3x = 9x 3(1)=3 3 \cdot (-1) = -3

  3. Combinar todos los términos obtenidos:

    6x22x+9x3 6x^2 - 2x + 9x - 3

  4. Simplificar combinando los términos semejantes:

    6x2+7x3 6x^2 + 7x - 3

Por lo tanto, la expresión expandida y simplificada es:

6x2+7x3 6x^2 + 7x - 3
