Answer: D. -3.2
Step-by-step explanation:
The correct answer to this question is D. -3.2 because when you subtract positive 8.8 and positive 12 your answer is -3.2.
(+8.8) - (+12) = -3.2
![{x}^{2} - \frac{15x}{2} + \frac{7}{2}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%20%20%5Cfrac%7B15x%7D%7B2%7D%20%20%20%2B%20%20%5Cfrac%7B7%7D%7B2%7D%20)
Step-by-step explanation:
So we go backwards, since we have x= 1/2 , 7
![(x - \frac{1}{2} )(x - 7)](https://tex.z-dn.net/?f=%28x%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%29%28x%20-%207%29)
Now we have to foil to get the quadratic
![{x}^{2} - 7x - \frac{1}{2} x + \frac{7}{2}](https://tex.z-dn.net/?f=%7Bx%7D%5E%7B2%7D%20%20-%207x%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20x%20%2B%20%20%5Cfrac%7B7%7D%7B2%7D%20)
We must simplify the terms
![{x}^{2} - \frac{14x}{2} - \frac{x}{2} + \frac{7}{2}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%20%20%5Cfrac%7B14x%7D%7B2%7D%20%20-%20%20%5Cfrac%7Bx%7D%7B2%7D%20%20%2B%20%20%5Cfrac%7B7%7D%7B2%7D%20)
Our final result comes out to be
![{x}^{2} - \frac{15x}{2} + \frac{7}{2}](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%20%20%5Cfrac%7B15x%7D%7B2%7D%20%20%20%2B%20%20%5Cfrac%7B7%7D%7B2%7D%20)
