How do i graph this hyperbola?

X^2+6x-3y^2=0

2 answers

complete the square
x^2 + 6x + 9 - 3y^2 = 9
(x+3)^2 - 3y^2 = 9
divide by 9
(x+3)^2 /9 - y^2/3 = 1

centre (-3,0)
a = 3, b = √3

vertices at (3,0) and (-3,0)
faintly sketch a rectangle with corners
at (±3,±√3)
draw in the diagonals and extend them
sketch the hyperbola with the diagonals as asymptotes and the vertices as noted above
except the whole thing is shifted 3 units to the left - because it's (x+3)^2
