Q. The equation of a parabola is y=x2+8x+17y = x^2 + 8x + 17. Write the equation in vertex form.\newlineWrite any numbers as integers or simplified proper or improper fractions.\newline______
  1. Identify Vertex Form: Identify the vertex form of a parabola. The vertex form of a parabola is given by y=a(xh)2+ky = a(x - h)^2 + k, where (h,k)(h, k) is the vertex of the parabola.
  2. Complete Square Transformation: Complete the square to transform the given equation into vertex form.\newlineThe given equation is y=x2+8x+17y = x^2 + 8x + 17. To complete the square, we need to find the value that makes x2+8xx^2 + 8x a perfect square trinomial. This value is (82)2=42=16(\frac{8}{2})^2 = 4^2 = 16. We will add and subtract 1616 inside the equation.
  3. Add and Subtract 1616: Add and subtract 1616 to the equation.\newliney=x2+8x+17y = x^2 + 8x + 17\newliney=x2+8x+16+1716y = x^2 + 8x + 16 + 17 - 16\newlineNow, we have added 1616 and subtracted 1616, which keeps the equation balanced.
  4. Rewrite Equation: Rewrite the equation by grouping the perfect square trinomial and combining the constants.\newliney=(x2+8x+16)+1716y = (x^2 + 8x + 16) + 17 - 16\newliney=(x+4)2+1y = (x + 4)^2 + 1\newlineNow, the equation is in vertex form, where (x+4)2(x + 4)^2 is the perfect square trinomial and 11 is the combined constant.
