Answer 2

Step-by-step explanation:

$Given : 7 {x}^{2} + 2 \sqrt{14x} + 2 \\ We \: can \: further \: write \: it \: as  \\ </p><p>7 {x}^{2} + 2 \sqrt{14x} + 2 = 7 {x}^{2} + \sqrt{2} \sqrt{78x} + 2 \\ \\ By \: taking \: out \: the \: common \: terms \\ 7 {x}^{2} + 2 \sqrt{14x} + \sqrt{7x} ( \sqrt{7x} + \sqrt{2} ) + \sqrt{2} ( \sqrt{7x} + \sqrt{2} ) \\ So \: we \: get \: , \\ 7 {x}^{2} + 2 \sqrt{214x} + 2 = ( \sqrt{7x} + \sqrt{2})( \sqrt{7x} + \sqrt{2} ) \\ It \: can \: also \: be \: written \: as  \\ 7 {x}^{2} + 2 \sqrt{214x} + 2 = ( \sqrt{7x} + \sqrt{2} {)}^{2}$
