What is the sum and product to this quadratic equation. x^2+7x+2=0

Pani-rosa [81]

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
