I don't know specifically what the sum and product of an equation is but
factor using quadratic formula
if you have an equation in ax^2+bx+c=0 then you can solve for x using
[tex]x= \frac{-b+ \sqrt{b^2-4ac} }{2a} [/tex] or [tex]x= \frac{-b- \sqrt{b^2-4ac} }{2a} [/tex]
so input
a=1
b=7
c=2
[tex]x= \frac{-7+ \sqrt{7^2-4(1)(2)} }{2(1)} [/tex]
[tex]x= \frac{-7+ \sqrt{49-8} }{2} [/tex]
[tex]x= \frac{-7+ \sqrt{41} }{2} [/tex]=aprox -0.2984378812836
[tex]x= \frac{-7- \sqrt{7^2-4(1)(2)} }{2(1)} [/tex]
[tex]x= \frac{-7- \sqrt{49-8} }{2} [/tex]
[tex]x= \frac{-7 \sqrt{41} }{2} [/tex]=aprox -6.7015621187165
