Question

If y = x² - 6x + 11 is written in the form y = a ( x - h )² + k, find the value of ( a + h + k).

Answer 1

y = X² - 6x + 11 is equal to...

y = 1 ( x +3)² + 20

therefore

a=1....h=3......k=20

(a + h + k) = 1 + 3 + 20 = 24..

Answer 2

6

Explanation:

y = x² - 6x + 11

Complete the square.

y = x² - 6x + 9 + 2

y = (x - 3)² + 2

a = 1, h = 3, k = 2

a + h + k = 6
