Question

sqrt 2x² + 7x + 5sqrt2 = 0 ( quadratic equation) class 10​

Answer 1

given

2x² + 7x + 5/sqrt{2} = 0

=================

solution=>

$= \sqrt{2} x {}^{2} + 7x + 5 \sqrt{2} \\ \\ = \sqrt{2}x {}^{2} + 2x + 5x + 5 \sqrt{2} \\ \\ = \sqrt{2}x(x + \sqrt{2} ) + 5(x + \sqrt{2}) \\ \\ = (\sqrt{2}x + 5) (x + \sqrt{2} ) \\ \\ = > \sqrt{2} x + 5 = 0 \\ \\ = > \sqrt{2} x = - 5 \\ \\ = > x = \frac{ - 5}{ \sqrt{2} } \\ \\and \\ \\ = > x + \sqrt{2 } = 0 \\ \\ = > x = - \sqrt{2}$
