Answer:

x1=3. x2=-2

Step-by-step explanation:

[tex]x = \frac{ - b + - \sqrt{b {}^{2} - 4ac } }{2a}[/tex]

b=-1

a=1

c=-6

[tex]x = \frac{ - ( - 1) + - \sqrt{ {( - 1)}^{2} - 4 \times 1 \times ( - 6) } }{2 \times 1} [/tex]

[tex]x = \frac{1 + - \sqrt{1 + 24} }{2} [/tex]

[tex]x = \frac{1 + - \sqrt{25} }{2} [/tex]

[tex]x1 = \frac{1 + 5}{2} [/tex]

[tex]x2 = \frac{1 - 5}{2} [/tex]

x1=3

x2=-2

[tex]x = \frac{1 + - 5}{2} [/tex]
