Hi I'm studying from home so sometimes there are parts that my course omits from teaching me, at which point I defer to the internet, so hi!
My question is referring to circles. Particularly the questions of the format:
1) Write down the radius and the co-ordinates to the centre of:
a) x
2 + y
2 + 3x - 5y + 2 = 0
These I am fine with however I am stuck when the x
2 and y
2 terms are given coefficients,
This is the exact question I am stuck on:
b) 3x
2 + 3y
2 + 6x - 4y - 15 = 0
Can someone please help?
Thank you
