Question

Найдите сумму и разность многочленов

Answer 1

$- 51 {k}^{4} + 10 \frac{3}{7} {c}^{2} + 12 \frac{3}{7} {c}^{2} + 1 9{ k}^{4} = - 32{k}^{4} + 22 \frac{6}{7} {c}^{2} \\ - - - - \\ - 51 {k}^{4} + 10 \frac{3}{7} {c}^{2} - ( 12 \frac{3}{7} {c}^{2} + 1 9{ k}^{4} ) = - 51 {k}^{4} + 10 \frac{3}{7} {c}^{2} - 12 \frac{3}{7} {c}^{2} - 1 9{ k}^{4} = - 70 {k}^{4} - 2 {c}^{2}$
$100 {s}^{5} + 31 \frac{5}{12} k + 40k - 92 .8{s}^{5} = 7.2{s}^{5} + 71 \frac{5}{12} k \\ - - - - - \\ 100 {s}^{5} + 31 \frac{5}{12} k - ( 40k - 92 .8{s}^{5}) = 100 {s}^{5} + 31 \frac{5}{12} k - 40k + 92 .8{s}^{5} = 192.8{s}^{5} - 8 \frac{7}{12} k$
