Q. Put the quadratic into vertex form and state the coordinates of the vertex.\newliney=x2+10x+16 y=x^{2}+10 x+16 \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=x2+10x+16y = x^2 + 10x + 16\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 1010, so we take half of it, which is 55, and then square it to get 2525.
  3. Add and Subtract: Add and subtract the square of half the coefficient of xx inside the equation.\newliney=x2+10x+2525+16y = x^2 + 10x + 25 - 25 + 16\newlineWe added and subtracted 2525 to complete the square, and then we can group the perfect square trinomial and the constants.
  4. Rewrite Equation: Rewrite the equation with the perfect square trinomial and combine the constants.\newliney=(x2+10x+25)9y = (x^2 + 10x + 25) - 9\newlineNow, we can write the perfect square trinomial as a squared binomial.\newliney=(x+5)29y = (x + 5)^2 - 9\newlineThis is the vertex form of the equation.
  5. Identify Vertex: Identify the vertex of the parabola.\newlineThe vertex form of the equation is y=(x+5)29y = (x + 5)^2 - 9.\newlineThe vertex (h,k)(h, k) can be read directly from the vertex form as (h,k)=(5,9)(h, k) = (-5, -9).
