Answer 1

Answer:

$3 - \sqrt{ 3 } - \sqrt{ 3 } - 1 = - 2 \left( \sqrt{ 3 } - 1 \right) \quad \left( \mathrm{ D e c i m a l : \quad } \: - 1 . 4 6 4 1 0 \dots \right)$

Step-by-step explanation:

$3 - \sqrt{ 3 } - \sqrt{ 3 } - 1$

$\gray{\mathrm{ A d d \: s i m i l a r \: e l e m e n t s : } \: - \sqrt{ 3 } - \sqrt{ 3 } = - 2 \sqrt{ 3 }}$

$= 3 - 2 \sqrt{ 3 } - 1$

$\gray{\mathrm{ S u b t r a c t \: t h e \: n u m b e r s : } \: 3 - 1 = 2 }$

$= 2 - 2 \sqrt{ 3 }$

$\gray{\mathrm{ F a c t o r \: o u t \: c o m m o n \: t e r m \: } - 2}$

$= - 2 \left( \sqrt{ 3 } - 1 \right)$
