We have many methods like completing the square method , Middle term splitting method , ... etc .
Let's go with middle term splitting method ,
➠ √2 x² + 7x + 5√2
On splitting the middle term , we get ,
➠ √2 x² + 2x + 5x + 5√2
➠ √2 x ( x + √2 ) + 5 ( x + √2 )
➠ ( x + √2 ) ( √2 x + 5 )
So ,
➠ ( x + √2 ) ( √2 x + 5 ) = 0
➠ x = - √2 ; x = - ⁵/√2
