Question

.

Answer 1

find discriminant

Answer 2

D=b^2-4ac

Answer 3

in ax^2+bx+c=0
d=b^2-4ac

Answer 4

if d<0,roots are not real.
if d=0,roots are real and equal.
if d>=0,roots are real and different.

Answer 5

a=1,b=-2,c=6
find d

Answer 6

d=4-24=-20<0
so no real roots.

Answer 7

@qwertykingGHLPO since the discriminant is less than zero, you'll have no real solutions because you can't take a square root of a negative number. You'll have what's called imaginary solution though.
