This is the original expression, so $$(y - 11)(y - 1)$$ is the correct factorisation. A quadratic expression can sometimes be factorised into two brackets in the form of \ ((x + a) (x + b)\) where \ (a\) and \ (b\) can be any term, positive, negative or zero. To check this answer is correct, expand out the brackets: $(y - 11)(y - 1) = (y \times y) + (y \times -1) + (-11 \times y) + (-11 \times -1)$.
