Question

15 баллов представьте в виде квадрата двухчлена трехчлен

Answer 1

$m^2+\frac{11}{6}m+\frac{121}{144}=(m+\frac{11}{12})^2\\\\\frac{9}{16}-\frac{3}{2}y+y^2=(\frac{3}{4}-y)^2\\\\n^2-\frac{9}{4}cn+\frac{81}{64}c^2=(n-\frac{9}{8}c )^2\\\\t^2-\frac{17}{5}dt+\frac{289}{100}d^2=(t-\frac{17}{10}d)^2$
