Question 1

what’s the standard equation for a circle

Answer 1

(x-h)^2 + (y-k)^2 = r^2

Question 2

how do you convert a circle equation to standard form general form

Answer 2

subtract non variable term, then separate terms by variable

Question 3

How do you find a perfect square

Answer 3

1. do your best to factor
2. take half of the coefficient (the one that is not squared) and divide it by 2
3. Square that number
4. subtract and add that number within the parenthesis
5. distribute
6. move the exponent to the outside and bam!

Question 4

in standard form, what is the center of the circle
(x-h)^2 + (y-k)^2 = r^2

Answer 4

(h,k)
