Question

Rewrite in vertex form: y=x^2+14x+50

Please help me understand.

Answer 1

hi, still need a hand?

Answer 2

to get the eqution into vertex form, we will need to 'complete the square' do you know how to do this?

Answer 3

No sir I do not lol, I'm just really messed up on this.

Answer 4

no problem, we can get you all set up.
here is what we are going to do,
we need to 'rewrite' this:
y=x^2+14x+50 which has a 'form' of
y=Ax^2+Bx+c

and we need to turn it into a 'form' of
y=a(x-h)^2 + k

do these 'forms' look familiar?

Answer 5

Yes they do, I seen that method before

Answer 6

ok then to rewrite the equation into the 'vertex form' we will 'complete the square'

Answer 7

we take the coefficient that is infront of the 'x' term, and divide it by 2
