Group x and y's
and comlete the sqare for each

x²+y²-2y-15=0
group
(x²)+(y²-2y)-15=0
take 1/2 of linear coefient and squaer it and add negative and positive iniside
-2/2=-1, (-1)²=1
(x²)+(y-2y+1-1)-15=0
factor prefect squares
x²+(y-1)²-1-15=0
x²+(y-1)²-16=0
add 16 to both sides
x²+(y-1)²=16
which can be rewritten in form
(x-0)²+(y-1)²=4²
center is at (0,1) and has a radius of 4

Anyone know how to solve this step by step?
ira [324]

Answer:

-1/2 or x=2

Step-by-step explanation: The first step you need to do in getting your answer is factoring ,you will factor the left side of the equation first:

(2x+1)(x-2)=0

Next, you will set the factors to equal to "0":

2x+1=0  x-2=0

Then you'll proceed to solve the problem using the basic algebraic equation problem solving steps .When you do this you'll be left with answers of x=-1/2  and x=2
