what did you get when you factored
rishavraj (rishavraj):
\[D > 0\] - two real and unequal solutions
\[D = 0 \] real and equal solutions
rishavraj (rishavraj):
\[D < 0 \] - no real roots
OpenStudy (omgthatgirl):
so its b
rishavraj (rishavraj):

D is negative

is that right?
rishavraj (rishavraj):
D = b^2 - 4ac
= 100 - 4(-25) (1)
= 100 + 100
= 200
OpenStudy (omgthatgirl):
ok pretty confusing
rishavraj (rishavraj):
as \[D > 0 \] it means 2 real and unequal solutions
OpenStudy (omgthatgirl):
so itts two solutions
