Answer 2

hello mate!......


given.........
$1) \: \: (m - \frac{10}{3} ) (m + \frac{7}{3} ) \\ \\ = m {}^{2} + \frac{7m}{3} - \frac{10m}{3} - \frac{70}{9} \\ \\ = m {}^{2} + \frac{7m - 10m}{3} - \frac{70}{9} \\ \\ = m {}^{2} - m - \frac{70}{9} \\ \\ \\ 2) \: ( \frac{1}{y} + 4)( \frac{1}{y} - 9) \\ \\ = \frac{1}{y {}^{2} } - \frac{9}{y} + \frac{4}{y} - 36 \\ \\ = \frac{1}{y {}^{2} } - \frac{ 5 }{y} - 36 \\ \\ hope \: i t \: helps \: u$
