Which is the vertex of x 2 + 10x = - 17?

(-5,-8)

Step-by-step explanation:

Given in the question an equation,

x² + 10x = - 17

x² + 10x + 17 = 0

here a = 1

        b = 10

        c = 17

Step 1

Find the value of x using the formula

x = -b/2a

x = -10/2

x = -5

Step 2

Find the value of y by plugging x = -5 in the equation above

(-5)² + 10(-5) + 17 = y

25 - 50 + 17 = y

y = -8

vertex (h,k) = (-5,-8)

true? is that what you're asking or do you mean something else?
