Question

Use the discriminant to determine the nature of the roots of 2x^2 = 0.

Answer 1

A.no real roots
B.one real root
C.two distint roots
D,three distinct root

Answer 2

\[D = b^2 - 4ac\]

Here, a = 2, b =c=0

So, D = 0

It has two but the same real roots..
So, one real root is the answer...
