Question

Rewrite the function y = x2 - 6x + 14 in vertex form, y = (x - h)2 + k.

Answer 1

divide the coefficient of x by 2 -6 / 2 = -3;

y = (x - 3)^2 + k
y = (x - 3)^2 - 9 + 14
y = (x-3)^2 + 5 is ur answer

Answer 2

y = x^2 - 6x + 14
y = x^2 - 2 . (x) . (3) + 9 + 5 ....... (using (a-b)^2 = a^2 -2ab+b^2)
y = (x - 3)^2 + 5 ...this is your answer
