Answer with Step-by-step explanation:
We know that
Number of zeroes of a quadratic function are 2.
When discriminant D
D=0
Roots are equal and real
D>0
Roots are real and different
D<0
Roots are not exist.
a.D=0
Number of zeroes=2
Zeroes are equal and real.
b.D=-36
Zeroes of quadratic function does not exist.
c.D=3
Number of zeroes=2
zeroes are real and different
d.D=2
Number of zeroes=2
zeroes are real and different
e.D=100
Number of zeroes=2
zeroes are real and different
D=-4
Zeroes of quadratic function does not exist.
