Question

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

Answer 1

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= (-b+ √(b^2-4ac) )/(2a)` or
`x= (-b- √(b^2-4ac) )/(2a)`

so input
a=1
b=7
c=2


`x= (-7+ √(7^2-4(1)(2)) )/(2(1))`

`x= (-7+ √(49-8) )/(2)`

`x= (-7+ √(41) )/(2)`=aprox -0.2984378812836


`x= (-7- √(7^2-4(1)(2)) )/(2(1))`

`x= (-7- √(49-8) )/(2)`

`x= (-7 √(41) )/(2)`=aprox -6.7015621187165
