Vertex/Axis of Symmetry for x^2+2x=35

Image to Crop Find the vertex, vertex form, and axis of symmetry for
x^2+2x=35

The quadratic you entered is not in standard form: ax2 + bx + c = 0

Subtract 35 from both sides

x2+2x - 35 = 35 - 35
x2+2x - 35 = 0

We have our a, b, and c values:
a = 1, b = 2, c = -35

Find the vertex, vertex form, and axis of symmetry of the quadratic
x2 + 2x - 35=

Vertex of a parabola

(h,k) where y = a(x - h)2 + kUse the formula rule.

Our equation coefficients are a = 1, b = 2

The formula rule determines h

h = Axis of Symmetry
h  =  -b
  2a

Plug in -b = -2 and a = 1

h  =  -(2)
  2(1)

h  =  -2
  2

h = -1  ← Axis of Symmetry

Calculate k

k = ƒ(h) where h = -1
ƒ(h) = (h)2(h)35=
ƒ(-1) = (-1)2(-1)35=
ƒ(-1) = 1 - 2 - 35
ƒ(-1) = -36
Our vertex (h,k) = (-1,-36)

Determine our vertex form:

The vertex form is: a(x - h)2 + k
Vertex form = (x + 1)2 - 36

h = -1
vertex (h,k) = (-1,-36)
Vertex form = (x + 1)2 - 36


What is the Answer?

h = -1
vertex (h,k) = (-1,-36)
Vertex form = (x + 1)2 - 36
