Complete the square to write the function in the form f(x) = a(x - h)? + + k.
f(x)= x2 - 8x + 17
f(x) =D
(Use integers or fractions for any numbers in the expression. Type an integer or an improper

Answer 1

Answer:

f(x) = (x-4)² + 1Step-by-step explanation:

For clarity, exponents should be marked with a ^:  f(x) = x^2 - 8x + 17

Group like terms

f(x) = (x² - 8x) + 17

Complete the square

 coefficient of x term: -8

 divide coefficient in half: -4

 square the result: (-4)² = 4²

 use 4² to complete the square and keep the equation balanced:

f(x) = (x² - 8x + 4²) - 4² + 17

f(x) = (x-4)² + 1
