Question

Anyone solve I make him brainlist​

Answer 1

Answer:

The given equation is x²+ax−4=0

Comparing given equation with ax²+bx+c=0

∴ a=1, b=a, c=−4

The discriminant of the given equation is given by D=b²−4ac=a²−4×−4=a² +16

Clearly, D=a²+16>0 for all a∈R

Hence, the given equation has real and distinct roots.

hope this helps you
