Answer 2

$\sf a² - b²$

$\sf \bigg( (\frac{1}{2} )^{2} -( \frac{3}{2} )^{2} \bigg)$

We can the identity of a² - b² = (a + b) (a - b)

$\sf \bigg( \frac{1}{2} + \frac{3}{2} \bigg)$

$\sf \bigg( \frac{1}{2} + \frac{3}{2} \bigg) \bigg( \frac{1}{2} - \frac{3}{2} \bigg)$

$\sf \bigg( \frac{4}{2} \bigg) \bigg( - \frac{2}{2} \bigg)$

$\sf -2$
