Answer 2

Answer:

Roots of a quadratic equation

ax² + bx + c = 0

is given by:

$x = \frac{ - b \: + \sqrt{ {b}^{2} - 4ac } } {2a} \: or \: \frac{ - b \: - \sqrt{ {b}^{2} - 4ac } }{2a}$

Here

a = 2, b = -10, c = 5

Substitute the values and you get

$x = \: \frac{ - 5 + \sqrt{15} }{2} \: or \: \frac{ - 5 - \sqrt{15} }{2}$
