Answer: 0.963
explanaontion :Step-by-step
divide value by 1000
The answer is 1
Use the discramnt formula
![{b {}^{2} - 4ac }](https://tex.z-dn.net/?f=%20%20%7Bb%20%7B%7D%5E%7B2%7D%20-%204ac%20%7D%20)
Where a is 81, B is 18, and c is 1
We get
![18 {}^{2} - 4(81)(1)](https://tex.z-dn.net/?f=18%20%7B%7D%5E%7B2%7D%20%20%20-%204%2881%29%281%29)
We then get 324-324=0
Which equal 0. Since the discramnt produce 0, the number of solution is one and repeated.
