Question

1) Determine nature of roots of the quadratic equation,
m2 + 2m +9 = 0.
Solution: compare mº + 2m +9 =0 with ax'+bx+c=0
a = 1, b = 2, c = 9
:b2 - 4ac = 22.4xx
D=4-O
D=-32
b2 - 4ac < 0
The roots of the equation are​

Answer 1

Answer:

m2+2m+9=0

am2+bm+c=0

a=1,b=2,c=9

b2-4ac=2×2-4×1×9

=-32

so roots are not real
