[tex]sum = - \frac{10}{ - 2} [/tex]
[tex]product = \frac{ - 20}{2} = - 10[/tex]
[tex]sum = \frac{ - 3}{2} = \frac{3}{2}[/tex]
[tex]product = \frac{ - 20}{2} = - 10[/tex]
[tex]sum = 18[/tex]
[tex]product = 0[/tex]
[tex]sum = \frac{ - 9}{2} = \frac{9}{2} [/tex]
[tex]product = \frac{ - 7}{2} = \frac{7}{2} [/tex]
[tex]sum = - \frac{ - 13}{4} = \frac{13}{4} [/tex]
[tex]product = \frac{12}{4} = 3[/tex]
