Question

what is
$(2 - \sqrt{3} )^{2}$
try if u can​

Answer 1

Answer:

$\large \: 7 - 4 \sqrt{3}$

Step-by-step explanation:

$\large \: (2 - \sqrt{3} )^{2}$

${(x - y)}^{2} = {x}^{2} + {y}^{2} - 2xy$

$\large \: (2 - \sqrt{3} )^{2} = {2}^{2} + \: { \sqrt{3} }^{2} - 2(2)( \sqrt{3} )$

$\large \: (2 - \sqrt{3} )^{2} = 4 + 3 - 4 \sqrt{3}$

$\large \: (2 - \sqrt{3} )^{2} = 7 - 4 \sqrt{3}$
