Answer 5

to find h, use the formula

h = -b/(2a)

Answer 6

x^2+4x+11 is really 1x^2+4x+11

1x^2+4x+11 is in the form ax^2+bx+c where a = 1, b = 4, c = 11

Answer 7

If you let f(x) = x^2+4x+11

then k = f(h)

Answer 8

Ok so then after that, what will the next step be

Answer 9

I stated all of the steps in a condensed form more or less

Answer 10

are you able to find h?

Answer 11

i got -2

Answer 12

good

Answer 13

how about k?

Answer 14

7

Answer 15

correct

Answer 16

(x-h)^2+k

then turns into what?

Answer 17

turns into (x-4)+7

Answer 18

you're missing something

Answer 19

and remember you found that h = -2

Answer 20

h isn't 4

Answer 21

oh the square!

Answer 22

(x-h)^2+k turns into (x-(-2))^2+7 which becomes (x+2)^2 + 7

Answer 23

ahhh ok i see my mistake nvm it makes sense! thanky uo!
