#((y-11))/(2(y+3))#

Explanation:

With algebraic fractions, try to find factors..

#(y^2-22y+121)/(2y^2-16y-66)" "(larr" quadratic trinomial")/(larr"common factor")#

#= ((y-11)(y-11))/(2(y^2-8y-33))" "(larr" factored")/(larr"quadratic trinomial")#

#= ((y-11)(y-11))/(2(y-11)(y+3))#

#= (cancel((y-11))(y-11))/(2(cancel(y-11))(y+3))#
