Answer:

Step-by-step explanation:

प्रश्नानुसार  

\sqrt 2 x^2 + x + \sqrt 2 = 0

यहाँ     a=\sqrt{2}

               b  = 1

             c   = \sqrt{2}

x=\frac{-b±\sqrt{b^{2}-4ac} }{2a} \\\\=\frac{-1±\sqrt{(1)^{2}-4*\sqrt{2} *\sqrt{2} } }{2*\sqrt{2} } \\\\=\frac{-1±\sqrt{1-4*2} }{2\sqrt{2} } \\\\=\frac{-1±\sqrt{1-8} }{2\sqrt{2} } \\\\=\frac{-1±\sqrt{-7} }{2\sqrt{2} }\\\\=\frac{-1±\sqrt{7}i }{2\sqrt{2} }

अतः  इसका हल =\frac{-1±\sqrt{7}i }{2\sqrt{2} }
