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

ganeshie8 (ganeshie8):

\(y = x^2-6x+14 \) \(y = x^2-2(3)x+9+5 \) \(y = (x-3)^2+5 \)

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

OpenStudy (anonymous):

its 5

OpenStudy (anonymous):

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 !

OpenStudy (anonymous):

thanks so much:)
