u knw how to complete the square ?
OpenStudy (anonymous):
kinda
ganeshie8 (ganeshie8):
good :) try completing the square
\(y = x^2-6x+14 \)
ganeshie8 (ganeshie8):
change that to the form,
\(y = a(x-h)^2 + k \)
k is the required y coordinate of vertex

\(y = x^2-6x+14 \)
\(y = x^2-2(3)x+9+5 \)
\(y = (x-3)^2+5 \)
OpenStudy (anonymous):
your just simplifying right?
ganeshie8 (ganeshie8):
ive just completed the square, now compare it wid
\(y = a(x-h)^2 + k\)
ganeshie8 (ganeshie8):
k is the required y-coordinate of the vertex

its 5

y=x^2-6x+14 implies y=(x-3)^2+5 thus the equation transforms as (y-5)=(x-3)^2
the vertex is (3,5)
ganeshie8 (ganeshie8):
5 = \(\checkmark\)
just may be have a look at how to complete the square and make urself convinced the final equation we got is correct :)
OpenStudy (anonymous):
so i just put 5 ?
ganeshie8 (ganeshie8):
yep !
