Question

use suitable identity to expand the following
$(\sqrt{2x +} \sqrt{3y} - \sqrt{5z}) {}^{2}$
​

Answer 1

Answer:

$2x + 3y + 5z + 2 \sqrt{6xy} - 2 \sqrt{15yz} - 2 \sqrt{10xz}$

Step-by-step explanation:

${( \sqrt{2x} + \sqrt{3y} - \sqrt{5z} )}^{2}$

$= 2x + 3y + 5z + 2 \sqrt{6xy} - 2 \sqrt{15yz} - 2 \sqrt{10xz}$
