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
\(x= \frac{-b+ \sqrt{b^2-4ac} }{2a}\) or \(x= \frac{-b- \sqrt{b^2-4ac} }{2a}\)
so input
a=1
b=7
c=2
\(x= \frac{-7+ \sqrt{7^2-4(1)(2)} }{2(1)}\)
\(x= \frac{-7+ \sqrt{49-8} }{2}\)
\(x= \frac{-7+ \sqrt{41} }{2}\)=aprox -0.2984378812836
\(x= \frac{-7- \sqrt{7^2-4(1)(2)} }{2(1)}\)
\(x= \frac{-7- \sqrt{49-8} }{2}\)
\(x= \frac{-7 \sqrt{41} }{2}\)=aprox -6.7015621187165
