The question:
$\displaystyle x^2 + y^2 = \frac{-(10x + 8)}{3}$
How would I go about writing this in a form which could find me the centre point and radius? Thanks.
$\displaystyle \displaystyle x^2 + y^2 = \frac{-(10x + 8)}{3}$
$\displaystyle \displaystyle x^2 + y^2 = -\frac{10}{3}x - \frac{8}{3}$
$\displaystyle \displaystyle x^2 + \frac{10}{3}x + y^2 = -\frac{8}{3}$.
Now complete the square on the $\displaystyle \displaystyle x$ terms.
