\[1)\ f(x) = (2x - 3)^{2}(x - 1);\]
\[f^{'}(x) = 2 \bullet 2(2x - 3)(x - 1) + (2x - 3)^{2};\]
\[f^{'}(1) = 4(2 - 3) \bullet 0 + (2 - 3)^{2} =\]
\[= ( - 1)^{2} = 1.\]
\[Ответ:\ \ 1.\]
\[2)\ f(x) = (x + 1)^{3}(x + 2);\]
\[f^{'}(x) = 3(x + 1)^{2}(x + 2) + (x + 1)^{3};\]
\[f^{'}(1) = 3 \bullet 2^{2} \bullet 3 + 2^{3} =\]
\[= 36 + 8 = 44.\]
\[Ответ:\ \ 44.\]
