Q. The equation of a parabola is y=x24x+5y = x^2 - 4x + 5. 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 the equation 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 in vertex form.\newlineWe have the equation y=x24x+5y = x^2 - 4x + 5. 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 4-4 is 2-2, and (2)2=4(-2)^2 = 4. So we add and subtract 44 within the equation.
  3. Add squared number: Add and subtract the squared number to the equation.\newliney=x24x+4+54y = x^2 - 4x + 4 + 5 - 4\newlineNow we have added 44 and subtracted 44, which keeps the equation balanced.
  4. Rewrite equation: Rewrite the equation by grouping the perfect square trinomial and combining the constants.\newliney=(x24x+4)+54y = (x^2 - 4x + 4) + 5 - 4\newliney=(x2)2+1y = (x - 2)^2 + 1\newlineNow the equation is in vertex form, where (x2)2(x - 2)^2 is the perfect square trinomial and 11 is the combined constant.
