Question

Change to standard circle form: 3x^2+3y^2+5x-4y=1

Answer 1

complete the squares for x and y. the remainder + 1 = radius

Answer 2

I don't know how to complete the square with coefficients attached to the variables with the 2nd degree.

Answer 3

you can look at it as 3(x^2 + 5x/3) + 3(y^2 - 4y/3) = 1

and complete the square inside the brackets :)

Answer 4

Would I need to multiple whatever I add inside by 3 and add it to the other side?

Answer 5

no. you can leave the 3 outside and forget about it. your answer will look like:

3(x + a/b)^2 + 3(y - c/d)^2 = e

Answer 6

Why wouldn't it be (x^2 + 5x/3) + (y^2 - 4y/3) = 1/3

Answer 7

you an also divide e by 3 to get rid of the 3's, in this case

Answer 8

merp

Answer 9

only because the coefficients are the same; rarely happens

Answer 10

(x+5/6)^2+(y-2/3)^2=53/36
Good or no good?
