To determine the range of values of
for which the quadratic equation
has two different roots, we need to examine the discriminant of the equation. The discriminant
is given by
.
In this case,
,
, and
. Plugging these values into the discriminant formula, we get:
For the quadratic to have two different roots, the discriminant must be positive:
Solving this inequality:
Additionally, we also need to be aware of the case when
becomes zero because then it wouldn’t be a quadratic equation anymore. Thus,
implies
.
So in conclusion, the quadratic equation has two different roots for:
