Find the vertices and foci of the hyperbola with equation quantity x plus 5 squared divided by 81 minus the quantity of y minus 3 squared divided by 144 = 1. Vertices: (4, 3), (-14, 3); Foci: (-20, 3), (10, 3) Vertices: (3, 7), (3, -17); Foci: (3, -17), (3, 7) Vertices: (7, 3), (-17, 3); Foci: (-17, 3), (7, 3) Vertices: (3, 4), (3, -14); Foci: (3, -20), (3, 10) @ganeshie8 @pooja195 @solomonzelman @zepdrix @paki @loser66 @luigi0210

But the 5 and -3 are telling us to shift this whole thing `5 left` and `3 up`.|dw:1436471197900:dw|

so let's start by finding some vertices.. hmm

The "center" of our hyperbola has been shifted to (-5,3). To find our vertex on the right branch, let's `add a` to the x-coordinate. We just want to move a distance of `a to the right` to get to the vertex. Do you understand what your `a` and `b` values are?

(3, 7), (3, -17) would this be our vertices? @zepdrix
