Answer 2

Answer:

x= {-8.76; -0.74}

Step-by-step explanation:

Use the Quadratic formula:

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

then substitute your values and start solving:

$x = \frac{ - 19 + - \sqrt{ {19}^{2} - (4 \times 2 \times 13)} }{2 \times 2} \\ x = \frac{ - 19 + - \sqrt{361 - 104} }{4}$

Eventually you will get:

$x = \frac{ - 19 + \sqrt{257} }{4} \\ or \\ x = \frac{ (- 19) - \sqrt{257} }{4}$

which is approximately:

$x = - 0.74219... \\ or \\ x = - 8.75780...$
