Final answer:
The real zeros of the quartic equation
are 1 and 2.78.
Step-by-step explanation:
A quadratic equation is a second-degree polynomial equation in a single variable, typically expressed as
where "x" represents the variable, and "a," "b," and "c" are constants.
The given equation is a quartic equation:

To find the real zeros, we can factor the equation or use synthetic division to test the given options.
Using synthetic division, we find that x = 1 and x ≈ 2.78 are the real zeros.
Therefore, the real zeros of the equation are 1 and 2.78.
