Answer:
Step-by-step explanation:
Given:
The quadratic function is given as:
The standard form of a quadratic function is given as:
, where, 'a', 'h' and 'k' are real numbers.
Now, in order to convert the given function to standard form, we use completing by square method.
![-x^2+2x=-(x^2-2x)=-[(x-2)^2-2^2]=-[(x-2)^2-4]=-(x-2)^2+4](https://tex.z-dn.net/?f=-x%5E2%2B2x%3D-%28x%5E2-2x%29%3D-%5B%28x-2%29%5E2-2%5E2%5D%3D-%5B%28x-2%29%5E2-4%5D%3D-%28x-2%29%5E2%2B4)
Now, can be rewritten as:
Therefore, the standard form of the function is:

Answer:
Step-by-step explanation:
5/6 - 8/7 - 7/10
The first step to adding or subtracting fractions is to find a common denominator among all the fractions. In this case, the largest number that has a mutiple of 6, 7 and 10 is 210.
\frac{5}{6}-\frac{8}{7}=\frac{7}{10}
-106/105
