Answer:
Answer: k must be 5/2 or 1
Step-by-step explanation:
![{ \tt{ - {2k}^{2} + 7k - 5 = 0}}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B%20-%20%20%7B2k%7D%5E%7B2%7D%20%20%2B%207k%20-%205%20%3D%200%7D%7D%20)
» Factorise the equation:
![{ \tt{ {2k}^{2} - 7k + 5 = 0 }} \\ { \tt{(2k - 5)(k - 1) = 0}} \\ \\ { \tt{k = \frac{5}{2} \: and \: 1 }}](https://tex.z-dn.net/?f=%7B%20%5Ctt%7B%20%7B2k%7D%5E%7B2%7D%20-%207k%20%2B%205%20%3D%200%20%7D%7D%20%5C%5C%20%20%20%7B%20%5Ctt%7B%282k%20-%205%29%28k%20-%201%29%20%3D%200%7D%7D%20%5C%5C%20%20%5C%5C%20%7B%20%5Ctt%7Bk%20%20%3D%20%20%5Cfrac%7B5%7D%7B2%7D%20%20%5C%3A%20and%20%5C%3A%201%20%7D%7D)
Answer:
-3
Step-by-step explanation:
![( - - 5) = + 5 \\ + ( - 8) = - 8 \\ 5 - 8 = - 3](https://tex.z-dn.net/?f=%28%20-%20%20-%205%29%20%3D%20%20%2B%205%20%5C%5C%20%20%2B%20%28%20-%208%29%20%3D%20%20-%208%20%5C%5C%205%20-%208%20%3D%20%20-%203)
