Q. The equation of a parabola is y=x24x+2y = x^2 - 4x + 2. 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.\newlineThe 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 the square: Complete the square to transform the given equation into vertex form.\newlineWe have the equation y=x24x+2y = x^2 - 4x + 2. To complete the square, we need to find the value that makes x24xx^2 - 4x a perfect square trinomial. We do this by taking half of the coefficient of xx, squaring it, and adding it to and subtracting it from the equation.\newlineHalf of the coefficient of xx is 4/2=2-4/2 = -2. Squaring this gives us (2)2=4(-2)^2 = 4. We add and subtract 44 to the equation.
  3. Add squared term: Add and subtract the squared term to the equation.\newliney=x24x+44+2y = x^2 - 4x + 4 - 4 + 2\newlineNow, we can rewrite the equation by grouping the perfect square trinomial and combining the constants.
  4. Rewrite in vertex form: Rewrite the equation in vertex form.\newliney=(x24x+4)4+2y = (x^2 - 4x + 4) - 4 + 2\newliney=(x2)22y = (x - 2)^2 - 2\newlineWe have now written the equation in vertex form, where (x2)2(x - 2)^2 is the perfect square trinomial and 2-2 is the combination of the constants.
