Find all complex solutions of X^2-5X -5= 0

denis-greek [22]

ANSWER

$x = \frac{ 5 - 3\sqrt{ 5} }{2} \: or \: x = \frac{ 5 +3 \sqrt{ 5} }{2}$

EXPLANATION

The given equation is

${x}^{2} - 5x - 5 = 0$

The solution is given by the formula

$x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a}$

where a=1, b=-5, c=-5

We substitute into the formula to get;

$x = \frac{ - - 5 \pm \sqrt{ {( - 5)}^{2} - 4(1)( - 5)} }{2(1)}$

We simplify to get,

$x = \frac{ 5 \pm \sqrt{ 45} }{2}$

The solutions are:

$x = \frac{ 5 - 3\sqrt{ 5} }{2} \: or \: x = \frac{ 5 +3 \sqrt{ 5} }{2}$

The equation has no complex roots.
