Solución
To determine the values of
for which the roots of the equation
are non-real, we need to analyze the right side of the equation.
-
Rearranging the equation:
We can rewrite the equation as:This is a quadratic equation in the form. -
Condition for non-real roots:
The roots of a quadratic equation are non-real if the discriminant is less than zero. The discriminantfor the equation can be expressed as: Here,, , and . Therefore, the discriminant becomes: -
Setting the condition for non-real roots:
We need to find when: Dividing both sides by 4 (which does not change the inequality since 4 is positive):Rearranging gives: -
Finding the values of
:
Taking the square root of both sides, we find:This means:
Thus, the values of
for which the roots of the equation are non-real are
or
.

The Deep Dive
To solve the equation
for the values of
for which the roots are non-real, let’s first express the condition for non-real roots.
The left-hand side,
, is always non-negative since it is a square term. For the roots to be non-real, the right-hand side must be negative:
This inequality can be rearranged:
Taking the square root of both sides, we find:
Thus, the values of
for which the roots of the equation are non-real are:
