Answer

The roots of the equation are non-real when or .

Solution

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.
  1. Rearranging the equation:
    We can rewrite the equation as:
    This is a quadratic equation in the form .
  2. Condition for non-real roots:
    The roots of a quadratic equation are non-real if the discriminant is less than zero. The discriminant for the equation can be expressed as:
    Here, , , and .
    Therefore, the discriminant becomes:
  3. 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:
  4. 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:
