(a + b)(a - b) = a² - b²
(3/5m + 1/2)(3/5m - 1/2) =
(3/5m)² - (1/2)² =
3²/5²m² - 1²/2² =
9/25m² - 1/4

Respuesta.
9/25m² - 1/4

Answer 2

Diferencia de cuadrados

$( \frac{3}{5m} + \frac{1}{2} ) ( \frac{3}{5m} - \frac{1}{2} )$

$(\frac{3}{5m} ) ^{ ^{2} } - (\frac{1}{2}) ^{ ^{2} }$

$\frac{9}{25 m^{2} } - \frac{1}{4}$
