Answer:

x1=3. x2=-2

Step-by-step explanation:

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

b=-1

a=1

c=-6

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

x =  \frac{1 +  -  \sqrt{1 + 24} }{2}

x =  \frac{1 + -   \sqrt{25} }{2}

x1 =  \frac{1 + 5}{2}

x2 =  \frac{1 - 5}{2}

x1=3

x2=-2

x =  \frac{1 +  - 5}{2}
