Answer:

(a - 2)(2a + 2) \\  =  {2a }^{2} + 2a - 4a - 4 \\  =  {2a}^{2}   - 2a - 4 \\  ({2a}^{2}  - 4a) + (2a - 4) \\ 2a(a - 2) + 2(a - 2) \\( a - 2)(2a + 2) \\ a = 2 \\ a =  - 1

dsp73
My teacher taught me rise over run. So, line A goes up one and to the side 4. That makes the slope 1/4. It's positive when the line goes up as you look to the right. C is a positive slope of 2. And D is - 2/3. Other than those two, you did a really good job!
