Find the center and vertices of the hyperbola.
11x^{2} -25y^2+22x+250y-889=0

Find the vertices and asymptotes of the hyperbola
9y^{2}-16x^2=144

Identify the conic by writing the equation in standard form.
4x^{2}+4y^2+40x+16y+40=0

Identify the conic. If it is a parabola, give the vertex. If it is a circle, give the center and radius. If it is an ellipse or a hyperbola, give the center and foci.
11x^{2}-3y^2-88x+18y+116=0

Subtract. Wirte the result in the form a+bi
(5 – 2i) – (6 + 8i)
