Q. Put the quadratic into vertex form and state the coordinates of the vertex.\newliney=x216x y=x^{2}-16 x \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 given equation y=x216xy = x^2 - 16x in vertex form.\newlineFirst, factor out the coefficient of the x2x^2 term, which is 11 in this case, so we can leave it as is.\newlineNext, take half of the coefficient of the xx term, which is 16-16, and square it to complete the square. \newlineHalf of 16-16 is 8-8, and (8)2=64(-8)^2 = 64.
  3. Add and subtract terms: Add and subtract the square of half the coefficient of xx inside the equation.\newliney=x216x+6464y = x^2 - 16x + 64 - 64\newlineWe added 6464 to complete the square and then subtracted 6464 to keep the equation balanced.
  4. Rewrite equation by grouping: Rewrite the equation by grouping the perfect square trinomial and the constant term.\newliney=(x216x+64)64y = (x^2 - 16x + 64) - 64\newliney=(x8)264y = (x - 8)^2 - 64\newlineNow the equation is in vertex form.
  5. Identify vertex: Identify the vertex of the parabola.\newlineThe vertex form of the equation is y=(x8)264y = (x - 8)^2 - 64.\newlineComparing this with the standard vertex form y=a(xh)2+ky = a(x - h)^2 + k, we find that h=8h = 8 and k=64k = -64.\newlineTherefore, the vertex of the parabola is (8,64)(8, -64).
