Question

What is the vertex form of the equation? Please just walk me through helping me :/ Thanks!

Answer 1

\(y=-x^2+12x-4\)

Answer 2

I know that I need to take out the -1:
\(y=-1(x^2-12x+4)\)

Answer 3

Factor -1 out of the first two terms on the right.

Answer 4

huh?

Answer 5

y=-1(x^2-12x + )+4

Answer 6

how did you get the +4 out of the parenthesis?

Answer 7

Make that +12x

Answer 8

Would it be ok to group the terms like this:
y=(-x^2+12x)-4

Answer 9

I don't know :/

Answer 10

It would. And having done so, factor -1 out of the first two terms:
y=-1(x^2-12x)-4

Answer 11

Okay

Answer 12

Now complete the square inside the parentheses by adding 36:
y=-1(x^2-12x+36)-4+36

Answer 13

okay one second...I need to write this down and show the work on that part....one second :)

Answer 14

Now factor and simplify:
y=-1(x-6)^2+32
And that is vertex form

Answer 15

okay thank you so much!

Answer 16

yw

Answer 17

Here,

Answer 18

I figured it out....Thank you anyways! I have to explain a bunch of stuff so I have to write a ton of work so I prefer the longer way :D
