so first we group like terms y^2+4x-6x-6y+5=0 y^2-6y-2x+5=0 so I suspect that you might have left out a x^2 but I'll try to solve it how it is
y^2-6y+5-2x=0 factor y^2-6y+5 what adds up to -6 and multiplies to get 5, -1 and -5 (y-5)(y-1)-2x=0 not sure how to procede but you could get it to this (y-5)(y-1)=2x
