Question

find the discrimant and the nature of the roots of quadratic equation . √2x²-3√5+√18=0​

Answer 1

Answer:

Given, 2x

2

−3x+5=0

Comparing with the standard quadratic equation is ax

2

+bx+c=0

Here, a=2, b=−3, c=5

Now, D=b

2

−4ac

=9−4×2×5

=−31

Here, the discriminant is negative.

Thus the quadratic question does not have any real roots.
