Full solution

Q. The equation of a parabola is y=x28x+23y = x^2 - 8x + 23. Write the equation in vertex form.\newlineWrite any numbers as integers or simplified proper or improper fractions.\newline______
  1. Complete the square: Complete the square for the xx-terms.(x28x+(82)2)(82)2+23(x^2 - 8x + (\frac{8}{2})^2) - (\frac{8}{2})^2 + 23
  2. Calculate value: Calculate (8/2)2(8/2)^2 which is 1616. \newline(x28x+16)16+23(x^2 - 8x + 16) - 16 + 23
  3. Combine like terms: Combine like terms 16+23-16 + 23 to get +7+7.\newline(x28x+16)+7(x^2 - 8x + 16) + 7
  4. Write in vertex form: Write the equation in vertex form.\newliney=(x4)2+7y = (x - 4)^2 + 7
