Answer 1

Объяснение:

$(2 + \frac{m}{m + 1} ) \times \frac{3 m {}^{2} + 3m}{12m + 8} =\left(\frac{2\left(m+1\right)}{m+1}+\frac{m}{m+1}\right)\times \left(\frac{3m^{2}+3m}{12m+8}\right) =\frac{2\left(m+1\right)+m}{m+1}\times \left(\frac{3m^{2}+3m}{12m+8}\right) =\frac{2m+2+m}{m+1}\times \left(\frac{3m^{2}+3m}{12m+8}\right) =\frac{3m+2}{m+1}\times \left(\frac{3m^{2}+3m}{12m+8}\right) =\frac{\left(3m+2\right)\left(3m^{2}+3m\right)}{\left(m+1\right)\left(12m+8\right)} =\frac{3m\left(m+1\right)\left(3m+2\right)}{4\left(m+1\right)\left(3m+2\right)} =\frac{3m}{4}$
