Question

Представьте в виде квадрата двучлена трехчлены

Answer 1

1)
$frac{4}{9} + frac{4}{3}a + {a}^{2} = {( frac{2}{3} + a)}^{2}$
2)
$frac{9}{25} + frac{6}{5}b + {b}^{2} = {( frac{3}{5} + b)}^{2}$
3)
$frac{16}{49} + frac{8}{7}c + {c}^{2} = {( frac{4}{7} + c)}^{2}$
4)
$frac{100}{121} {k}^{2} - frac{20}{11}tk + {t}^{2} = {( frac{10}{11}k - t)}^{2}$
5)
${m}^{2} - frac{22}{13}mn + frac{121}{169} {n}^{2} = {(m - frac{11}{13}n)}^{2}$
6)
$frac{400}{441} {t}^{2} + frac{40}{21}nt + {n}^{2} = {( frac{20}{21}t + n)}^{2}$
