A. \(\frac{{ - 13{x^2} - 10x + 1}}{{{{({x^2} - 5x + 2)}^2}}}\)
B. \(\frac{{ - 13{x^2} + 5x + 11}}{{{{({x^2} - 5x + 2)}^2}}}\)
C. \(\frac{{ - 13{x^2} + 5x + 1}}{{{{({x^2} - 5x + 2)}^2}}}.\)
D. \(\frac{{ - 13{x^2} + 10x + 1}}{{{{({x^2} - 5x + 2)}^2}}}.\)
D
\(y = \frac{{2{x^2} + 3x - 1}}{{{x^2} - 5x + 2}}.\)
\(y' = \frac{{{{\left( {2{x^3} + 3x - 1} \right)}'}\left( {{x^2} - 5x + 2} \right) - \left( {2{x^3} + 3x - 1} \right){{\left( {{x^2} - 5x + 2} \right)}'}}}{{{{\left( {{x^2} - 5x + 2} \right)}^2}}}.\)
\(y' = \frac{{\left( {6{x^2} + 3} \right)\left( {{x^2} - 5x + 2} \right) - \left( {2{x^3} + 3x - 1} \right)\left( {2x - 5} \right)}}{{{{\left( {{x^2} - 5x + 2} \right)}^2}}} = \frac{{ - 13{x^2} + 10x + 1}}{{{{({x^2} - 5x + 2)}^2}}}.\)
