Question

for the following equation find the discriminant and describe nature of the solutions
-14x^2-7x+17

Answer 1

i know ;)

Answer 2

the discriminat is the radicand from the quadratic formula\[b^2-4ac\]where\[ax^2+bx+c=0\]
in you problem\[b^2-4ac=49-4(-14)(17)=1001\]which is positve but not a perfect square, so there are "two real roots"

Answer 3

ok, i was sure if i had the radicand thing right, thanks!

Answer 4

assuming a, b, c are rational numbers

b^2-4ac Number & Nature of Roots
====== ================
0 one double real root
>0 two real roots
<0 two complex roots

Answer 5

ur welcome :})
