+1223 Complete the square.
\(5x^2 - 20x + 1357 = 5(x-2)^2 + 1337\).
So, the minimum value is 1337.

Here's another approach
In the form ax^2 + bx + c......the x value that minimizes the function is given by - b / (2a)
So b = - 20 a = 5
- b / (2a) = -(-20) / (2*5) = 20 / 10 = 2
Put this back into the function to find the the min
5(2)^2 -20(2) + 1357 =
20 - 40 + 1357 =
1337
