Use the Distributive property to rewrite the polynomial (x+8) (x-2).

□x²+□x+□

1 answer

To use the Distributive Property (also known as the FOIL method for binomials) to rewrite the polynomial \((x + 8)(x - 2)\), we need to multiply each term in the first binomial by each term in the second binomial.

Here’s the step-by-step calculation:

  1. First terms: Multiply the first terms in each binomial: \[ x \cdot x = x^2 \]

  2. Outer terms: Multiply the outer terms: \[ x \cdot (-2) = -2x \]

  3. Inner terms: Multiply the inner terms: \[ 8 \cdot x = 8x \]

  4. Last terms: Multiply the last terms in each binomial: \[ 8 \cdot (-2) = -16 \]

Now, we combine all these results: \[ x^2 - 2x + 8x - 16 \]

Next, combine the like terms \(-2x + 8x\): \[ x^2 + 6x - 16 \]

So, the polynomial \((x + 8)(x - 2)\) rewritten using the Distributive Property is: \[ x^2 + 6x - 16 \]

Thus, filling in the blanks as requested: □x² + □x + □ would be:

  1. \(1\) for the \(x^2\) coefficient
  2. \(6\) for the \(x\) coefficient
  3. \(-16\) as the constant term.

So the answer is:

  1. 1, 6, -16.
