​

Answer 1

HEY BUDDY ♥

HERE'S THE ANSWER ✌

⤵⤵⤵⤵⤵

$( - 3 + \sqrt{5} )( - 3 - \sqrt{5} )$

using formula,

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

$( - 3 )^{2} - ( \sqrt{5} ) ^{2}$

$9 - 5$

$4 \: \: \: \: \: \: \: \: answer$

Answer 2

$(-3+ \sqrt{5} ) (-3- \sqrt{5} )$

$= (9+ 3\sqrt{5}- 3\sqrt{5}- 5 )$

$= (9- 5) \\= (4)$
