Question

How many and of what type are the solutions to x2 + 9x + 10 = 0?
Answer
No real solutions
Two identical rational solutions
Two different rational solutions
Two irrational solutions

Answer 1

use b^-4ac do determine that...

a=1
b=9
c=10

if b^2-4ac = 0, then you have 1 real solution... yes, for real....:)
if b^2-4ac is positive, then you have 2 real solutions...
if b^2-4ac is negative, then you have 2 complex solutions..., naw complex doesn't mean it's hard.... :)
