Answer 2

Answer:

${1 + tan \: a}^{2}$

${1}^{2} + {tan \: a}^{2} + 2(tan \: a)(1)$

$1 + {tan}^{2} a + 2 \: tan \: a \:$

${tan}^{2} a + 2tan \: a + 1$

${tan}^{2} a + tan \: a \: + tan \: a \: + 1$

$({tan}^{2} a \: + tan \: a) + (tan \: a + 1)$

$tan \: a(tan \: a + 1) + 1(tan \: a + 1)$

$(tan \: a + 1)(tan \: a + 1)$

tan a =-1,-1
