Q. Put the quadratic into vertex form and state the coordinates of the vertex.\newliney=x24x32 y=x^{2}-4 x-32 \newlineVertex Form: y= y= \newlineVertex: (,) (\square, \square)
  1. Identify vertex form: Identify the vertex form of a parabola.\newlineThe vertex form of a parabola is y=a(xh)2+ky = a(x - h)^2 + k, where (h,k)(h, k) is the vertex of the parabola.
  2. Complete the square: Complete the square to rewrite the quadratic equation in vertex form.\newlineGiven equation: y=x24x32y = x^2 - 4x - 32\newlineTo complete the square, we need to find a value that, when added and subtracted to the equation, forms a perfect square trinomial.\newlineThe coefficient of xx is 4-4, so we take half of it, which is 2-2, and then square it to get 44.\newlineWe add and subtract 44 inside the equation to complete the square.
  3. Add and subtract values: Add and subtract the value found inside the parentheses.\newliney=x24x+4432y = x^2 - 4x + 4 - 4 - 32\newlineNow, group the perfect square trinomial and the constants.\newliney=(x24x+4)36y = (x^2 - 4x + 4) - 36
  4. Factor perfect square trinomial: Factor the perfect square trinomial.\newliney=(x2)236y = (x - 2)^2 - 36\newlineNow we have the equation in vertex form.
  5. Identify vertex: Identify the vertex of the parabola.\newlineThe vertex form of the equation is y=(x2)236y = (x - 2)^2 - 36.\newlineComparing this with the standard vertex form y=a(xh)2+ky = a(x - h)^2 + k, we find that h=2h = 2 and k=36k = -36.\newlineTherefore, the vertex of the parabola is (2,36)(2, -36).
