Determine the nature of the roots of the following quadratic equations:

$2x^2 - 3x + 5 = 0$

Given:

Given quadratic equation is $2x^2 - 3x + 5 = 0$.

To do:

We have to determine the nature of the roots of the given quadratic equation.

Solution:

Comparing the given quadratic equation with the standard form of the quadratic equation $ax^2+bx+c=0$, we get,

$a=2, b=-3$ and $c=5$.

The discriminant of the standard form of the quadratic equation $ax^2+bx+c=0$ is $D=b^2-4ac$.

Therefore,

$D=(-3)^2-4(2)(5)=9-40=-31$.

As $D<0$, the given quadratic equation has no real roots.
