What value of x will give the minimum value for x^2 + 11x - 5?

Thanks so much for all your help

In the form ax^2 + bx + c the x value that will give the minimum is

-b / [ 2a]

So we have x^2 + 11x - 5

a = 1 b = 11

So

-b / [2a] = - 11 / [ 2 * 1] = - 11 / 2

And this is the x value that minimizes the function

:D 👍
