Option #1: 2x(x−4x−5) Option #2: (2x+2)(x−5) Option #3: 2x(x−5)+2(x−5) Option #4: (x−5)(x−3) Option #5: −6x−10 (1 point) Option # and Option #. What’s the answer

1 answer

To determine which options might be equivalent or provide a related answer, we can simplify each of the given options.

Option #1: \( 2x(x - 4x - 5) \)

  1. Simplify inside the parentheses: \[ x - 4x - 5 = -3x - 5 \]
  2. Expanding: \[ 2x(-3x - 5) = -6x^2 - 10x \]

Option #2: \( (2x + 2)(x - 5) \)

  1. Expand: \[ 2x \cdot x - 5(2x) + 2 \cdot x - 5 \cdot 2 = 2x^2 - 10x + 2x - 10 = 2x^2 - 8x - 10 \]

Option #3: \( 2x(x - 5) + 2(x - 5) \)

  1. Factor out \( (x - 5) \): \[ (2x + 2)(x - 5) \]
  2. Expanding (which is the same as Option #2): \[ 2x^2 - 8x - 10 \]

Option #4: \( (x - 5)(x - 3) \)

  1. Expand: \[ x^2 - 3x - 5x + 15 = x^2 - 8x + 15 \]

Option #5: \( -6x - 10 \) This is already simplified.

Now we can summarize the simplified results:

  • Option #1: \( -6x^2 - 10x \)
  • Option #2: \( 2x^2 - 8x - 10 \)
  • Option #3: \( 2x^2 - 8x - 10 \)
  • Option #4: \( x^2 - 8x + 15 \)
  • Option #5: \( -6x - 10 \)

From the above simplifications, we see that:

  • Option #2 and Option #3 are equal.

So the answer is: Option #2 and Option #3.
