$⟹</p><p>2 {x}^{2} - 27$

$⟹</p><p> { (\sqrt{2x} )}^{2} - {(3 \sqrt{3} )}^{2}$

It is the form of a^2-b^2

$⟹</p><p> {a}^{2} - {b}^{2} = (a + b)(a - b)$

$⟹</p><p>So, {( \sqrt{2x} )}^{2} - {(3 \sqrt{3}) }^{2} = ( \sqrt{2}x + 3 \sqrt{3} )( \sqrt{2} x - 3 \sqrt{3} )$

$</p><p>∴2 {x}^{2} - 27 = ( \sqrt{2} x + 3 \sqrt{3} )( \sqrt{2} x - 3 \sqrt{3} )$
