Standard form of the hyperbola equation :
#(y-7)^2/100-(x+9)^2/100=1#.

The standard form of a hyperbola with centre, #(alpha,beta)# is #rarr#

#(y-beta)^2/b-(x-alpha)^2/a=1#

Therefore, the given expression can be arranged as #rarr#

#-(x^2+18x+81)+(y^2-14y+49)=(132-81+49)#

#:.(x+9^2)-(y-7)^2=-100#

#:.((x+9)^2/-100)-((y-7)^2/-100)=1#

#:.(y-7)^2/100-(x+9)^2/100=1#. (Answer).

Hope it Helps:)
