x² + 7 > 0 với mọi x => căn thức \(\sqrt{x^2+7}\) luôn xác định

PT <=> (x² + 7) + 4x = x. \(\sqrt{x^2+7}\) + 4. \(\sqrt{x^2+7}\)

<=> [(x² + 7) -  x. \(\sqrt{x^2+7}\)] + [4x -  4. \(\sqrt{x^2+7}\)]  = 0

<=> \(\sqrt{x^2+7}\). [\(\sqrt{x^2+7}\) - x] + 4. [ x - \(\sqrt{x^2+7}\)] = 0 

<=> [ x - \(\sqrt{x^2+7}\)] . [4 -  \(\sqrt{x^2+7}\)]  = 0 

<=>  x - \(\sqrt{x^2+7}\) = 0  hoặc 4 -  \(\sqrt{x^2+7}\) = 0 

+) 4 -  \(\sqrt{x^2+7}\) = 0 <=> x² + 7 = 16 <=> x² = 9 <=> x = 3 hoặc x = -3

+) x - \(\sqrt{x^2+7}\) = 0 : Vô nghiệm vì \(\sqrt{x^2+7}\) >  \(\sqrt{x^2}\) = |x| >= x => x - \(\sqrt{x^2+7}\) < 0 với mọi x

Vậy PT có 2 nghiệm x =3  hoặc x = -3
