Question

write an equation of the circle with center (-2,-3) and radius 8
i did
x^2+4+y^2+9=64

Answer 1

nope

Answer 2

why not the standard quation is (x-h)^2+(y-k)^2=r^2 and i plugged in the values

Answer 3

circle equation
\[(x-x_o)^2+(y-y_o)^2=r^2\]
if i remembered correctly

anyways \[(x+2)^2 \ne x^2+4\]

Answer 4

you used the right equation, you just "foil"ed incorrectly

Answer 5

ohhh i get it
(x+2)(x+2)

Answer 6

yup
