Question

solve 3n^2+17n+10=0
a. n = -2/3 or n = -5
b. n = -2/3 or n = 3
c. n = 0 or n = 5
d. n = -5 or n = 3

Answer 1

To solve this, use the commonly known quadratic formula. 

-b +/- sqrt ( b^2 - 4ac )
-------------------------------
               2a

So plug in the numbers, and you should get 

(a=3 b=17 c=10)

a.)  -2/3 or -5
