Answer 1

Answer:

HOPE THIS HELPS YOU

THANK YOU

Step-by-step explanation:

The given equation is x

2

+ax−4=0

Comparing given equation with ax

2

+bx+c=0

∴a=1,b=a,c=−4

The discriminant of the given equation is given by D=b

2

−4ac=a

2

−4×−4=a

2

+16

Clearly, D=a

2

+16>0 for all a∈R

Hence, the given equation has real and distinct roots.
