Explanation:
To find the discriminant of an equation,
first, you must make the equation into the form of
And the discriminant will be
if the discriminant =0,then the equation has two equal real roots
if the discriminant >0,the the equation will have two different real roots
if the discriminant < 0, the the equation will have no real roots.
so based on the given equation
we can write out that
discriminant=
=-0.07
because the discriminant of the equation is < 0
so we can tell that the equation has no real roots.
