Ответ:

$y '= \frac{(x + 3) '{(x - 1)}^{2} - ( {(x - 1)}^{2} ) '\times (x + 3)}{ {(x - 1)}^{4} } = \\ = \frac{1 \times {(x - 1)}^{2} - 2(x - 1)(x + 3)}{ {(x - 1)}^{4} } = \\ = \frac{(x - 1)(x - 1 - 2(x + 3))}{ {(x - 1)}^{4} } = \\ = \frac{x - 1 - 2x - 6}{ {(x - 1)}^{3} } = \frac{ - x - 7}{ {(x - 1)}^ {3} } = \\ = - \frac{ x + 7}{ {(x - 1)}^{3} }$
