Q. Put the quadratic into vertex form and state the coordinates of the vertex.\newliney=x212x+20 y=x^{2}-12 x+20 \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=x212x+20y = x^2 - 12x + 20\newlineTo complete the square, we need to find a value that makes x212x+___x^2 - 12x + \_\_\_ a perfect square trinomial.\newlineThe value needed is (122)2=62=36(\frac{12}{2})^2 = 6^2 = 36.
  3. Add and Subtract Values: Add and subtract the value found inside the equation.\newliney=x212x+3636+20y = x^2 - 12x + 36 - 36 + 20\newlineNow, we have added 3636 to complete the square, but we must also subtract 3636 to keep the equation balanced.
  4. Rewrite Equation: Rewrite the equation with the perfect square trinomial and the constants combined.\newliney=(x212x+36)16y = (x^2 - 12x + 36) - 16\newliney=(x6)216y = (x - 6)^2 - 16\newlineNow the equation is in vertex form.
  5. Identify Parabola Vertex: Identify the vertex of the parabola.\newlineThe vertex form of the equation is y=(x6)216y = (x - 6)^2 - 16.\newlineComparing this with the vertex form y=a(xh)2+ky = a(x - h)^2 + k, we find that h=6h = 6 and k=16k = -16.\newlineTherefore, the vertex of the parabola is (6,16)(6, -16).
