Question

I've tried this and can't figure it out. Can someone please show me how to do it?


Use the information provided to write the vertex form equation of each parabola.
y=2x^2+36x+170

Answer 1

?

Answer 2

Sorry @alivejeremy I just added it!

Answer 3

first, factor out the 2. can you do that ?

Answer 4

in
y=2x^2+36x+170
do you see that you can divide 2 into each term evenly ?

Answer 5

yes

Answer 6

so
y=2(x^2+18+85)

Answer 7

yes, if you put in the missing x

Answer 8

oh yea sorry

Answer 9

next, we concentrate on just the
(x^2 + 18x + 85)

we want to "complete the square"
what that means is we add and subtract the square of half of the middle number
