Question

Complete the square and write equation in standard form and give center and radius. -___-

Answer 1

x^2+y^2+2x+8y+17=19

Answer 2

I gathered like terms if anything x^2=2x, y^2+8y and 9-17=2

Answer 3

2x
(x+a)^2=x^2+2*x*a+a^2
since you have just 2x then a =1

Answer 4

Ok that part I got lost @AJ01

Answer 5

okay
you have Y^2 and 8y in the equation

Answer 6

Uh huh!

Answer 7

stander form (y+b)^2

Answer 8

(y+b)^2=y^2+2yb+b^2

Answer 9

is that clear

Answer 10

um, I just don't know where you got b from, the equation right?

Answer 11

Teaching me math is really hard lol

Answer 12

it is okay..... b: any number that i don't know yet

Answer 13

ok

Answer 14

Ok. My bad trying to piece things together

Answer 15

(y+b)^2=y^2+2yb+b^2
in the equation above you have 8y

Answer 16

What's the name of that formula?

Answer 17

8y has to equal 2yb
solve for b
2by=8y
b=8y/2y=4

Answer 18

Why did you pick 8?

Answer 19

Quadratic Formula Explained
(x-a)^+(y-b)^=r^2

Answer 20

(x-a)^2+(y-b)^2=r^2
x^2-2ax+a^2+y^2-2by+b^2=r^2

Answer 21

the equation you have like this one i want put back to the stander form..... so
2by has to equal something with y

Answer 22

Woah

Answer 23

Okay!

Answer 24

x^2+y^2+2x+8y+17=19
you need (1) for x form and (16) for the y form
(x+1)^2+(y+4)^2=19

Answer 25

OMG MY BAD the 19 is a 9!

Answer 26

okay then 3^2

Answer 27

(x+1)^2+(y+4)^2=3^2
Explained this
X^2+2x+1+y^2+8y+16=9
x62+2x+y^2+8y+17=9

Answer 28

That is all?
