(6a^2-3a+11)-(-3a-a^3+7)

(3/5m^3h^2-1/4mn^2)-(-5/8n^2m+7/10m^3n^2)

Answer 1

$(6a^2-3a+11)-(-3a-a^3+7)=6a^2-3a+11+3a+a^3-7=a^3 + 6a^2 + 4$

$(\frac{3}{5}m^3h^2-\frac{1}{4}mn^2)-(-\frac{5}{8}n^2m+\frac{7}{10}m^3n^2)=$

$\frac{3}{5}m^3h^2-\frac{2}{8}mn^2+\frac{5}{8}mn^2-\frac{7}{10}m^3n^2=$

$\frac{3}{5}m^3h^2+\frac{3}{8}mn^2-\frac{7}{10}m^3n^2$
