Question

The roots is the Quadratic equation 2x^2-2√2x+1=0 are...​

Answer 1

$2 {x}^{2} - 2 \sqrt{2} x + 1 = 0 \\ we \: know \: x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ hance \\ x = \frac{ - 2 \sqrt{2} + - \sqrt{ {2 \sqrt{2} }^{2} - 4 \times 2 \times 1 } }{2 \times 2 } \\ final \: value \\ x = 0.7$

BOTH ROOTS ARE SAME
