According to the Distributive Property, which is a way to rewrite the algebraic expression (3x−1)(x−4) ?

1 answer

The Distributive Property states that \( a(b + c) = ab + ac \). To apply this property to the expression \( (3x - 1)(x - 4) \), we need to distribute each term in the first factor to each term in the second factor.

Let's do this step by step:

  1. Distribute \( 3x \) to both terms in \( (x - 4) \):

    • \( 3x \cdot x = 3x^2 \)
    • \( 3x \cdot (-4) = -12x \)
  2. Distribute \( -1 \) to both terms in \( (x - 4) \):

    • \( -1 \cdot x = -x \)
    • \( -1 \cdot (-4) = 4 \)

Now, combine all these results together: \[ 3x^2 - 12x - x + 4 \]

Next, combine the like terms \( -12x \) and \( -x \): \[ 3x^2 - 13x + 4 \]

So, the expression \( (3x - 1)(x - 4) \) can be rewritten as: \[ 3x^2 - 13x + 4 \]
